Details
Torque or Turning Force: It is the total amount of force which is required to create acceleration on moving substance.

Couple: Two forces those acts on equally,parallely & oppositely on two separate points of same material.
Moment: It is the amount of moving effect which is gained for action of turning force.
Stress: It is the force that can prevent equal & opposite force. That means, it is the preventing force.  If one force acts on outside of a material, then a reactive force automatically acts to protest that force. The amount of reactive force per unit area is called stress. e.g. Tensile Stress, Compressive Stress, Thermal Stress.

Strain: If a force acts on a substance, then in that case if the substance would deform. Then the amount of deformation per unit length of that substance is called strain.

Spring: It is one type of device which is being distorted under certain amount of load & also can also go to its original face after the removal of that load. Its function:

• To store energy.
• To absorb energy.
• To control motion of two elements.

Stiffness: Load per unit deflection. The amount of load required to resist the deflection.

Specific Weight: Weight per unit volume of the fluid.
Specific Volume: Volume per unit mass of the fluid.

Specific Gravity: It is the ratio of specific weight of required substance to specific weight of pure water at 4 degree centigrade temperature.
Specific heat: The amount of heat required to increase 1 unit temperature of 1 unit mass.

Viscosity:

• Dynamic Viscosity: The amount of resistance of one layer of fluid over other layer of fluid.
• Kinematic Viscosity: It is the ratio of dynamic viscosity to density.

Buoyancy: When a body is immersed in a liquid, it is lifted up by a force equal to weight of liquid displaced by the body. The tendency of liquid to lift up an immersed body is buoyancy. The upward thrust of liquid to lift up the body is called buoyancy force.
Bernoulli's Equation:
P/γ +V²/2g +Z = Constant
Where, P = pressure,V = velocity,Z = Datumn Head

Devices for fluid:

• Venturimeter: It measures discharge of fluid.
• Notches : It measures discharge of fluid.
• Orifice meter: It measures discharge of fluid.
• Pitot tube : It measures velocity of fluid.

Mach Number: It is the ratio of the velocity of fluid to the velocity of
sound.
M=1 ----------------- Sonic flow
M> (1-6) ----------- Super-Sonic flow
M>6 ---------------- Hyper-Sonic flow

Fluid discharge/Fluid flow: Quantity of fluid flowing per second. (through a section of pipe/ through a section of channel)
Q=AV
where, V= velocity of fluid,A= cross-sectional area of pipe/channel
Note: 1m³ = 1000 L1 cusec = 1 ft³/sec1 ft = 0.3048 m.

Hydraulic Machine:
Turbine,Pump,Compressor etc.
Draft tube:
It attaches with reaction turbine . Its function is to reduce energy loss from reaction turbine & it also reduce pressure at outlet which is must blow the atmospheric pressure.

Themodynamics Law:

• Zeroth Law
• First Law of Thermodynamic
• Second Law of thermodynamic

Zeroth Law: If two body are in thermal equilibrium with a third body then these two body are also in thermal equilibrium with each other.
First Law of Thermodynamics: In a closed system, work deliver to the surrounding is directly proportonal to the heat taken from the surrounding.And also, In a closed system, work done on a system is directly proportonal to the heat deliver to the surrounding.
Second Law of Thermodynamics: It is impossible to make a system or an engine which can change 100 percent input energy to 100 percent output.

Entropy: It is a thermodynamic property.
ds = dq/T
where, ds = change of entropy, dq = change of heat,
T = Temperature.
In adiabatic process, entropy can not change. Actually,lacking or mal-adroitness of tranfering energy of a system is entropy.

Calorific Value of fuel:
It us the total amount of heat obtained from burning 1 kg solid or liquid fuel.
Boiler/Steam

• Generator: It is a clossed vessel which is made of steel. Its function is to transfer heat to water to generate steam.
• Economiser: It is a part of boiler. Its function is to heat feed water which is supplied to boiler.
• Superheater: It is a part of boiler. Its function is to increase temperature of steam into boiler.
• Air-Preheater: It is a part of boiler. Its funtion is to preheats the air to be supplied to furnace and it recover heat from exhaust gas.
• Boler Draught: It is an important term for boiler. It is the difference of pressure above and below the fire grate. This  pressure difference have to maintain very carefully inside the bolier. It actually maintaind the rate of steam generation. This depends on rate of fuel burning. Inside the boiler rate of fuel burning is maintained with rate of entry fresh air. If proper amount of  fresh air never entered into the boiler, then proper amount of fuel inside the boiler never be  burnt. So, proper fresh air enters into the boiler only by maintaining boiler draught.

Nozzle: Nozzle is a duct of varying cros-sectional area. Actually, it is a passage of varying cross-sectional area. It converts steam's heat energy into mechanical energy. It is one type of pipe or tube that carrying liquid or gas. Scavenging: It is the process of removing burnt gas from combustion chamber of engine cylinder.
Supercharging: Actually, power output of engine depends on what amount of air enter into the engine through intake manifold. Amount of entry aiy if increased, then must be engine speed will increased. Amount of air  will be increased by increasing inlet air density. The process of increasing inlet air density is supercharging. The device which is used for supercharging is called supercharger.Superchargeris driven by a belt from engine crakshaft. It is installed in intake system. Turbocharging: Turbocharging is similar to the supercharging. But in that case tubocharger is installed in exhaust system whereas supercharger is installed in intake system. Turbocharger is driven by force of exhaust gas. Generally, turbocharger is used for 2-stroke engine by utilizing exhaust energy of the engine, it recovers energy otherwise which would go waste..
Governeor: Its function id to regulate mean speed of engine when there are variation in the load. If load incrases on the engine, then engine's speed must decrease. In that case supply of working fluid have to increase. In the otherway, if load decrease on the engine, then engine' speed must increase. In that case supply of working fluid have to decrease.Governor automatcally, controls the supply of working fluid to the engine with varying load condition.

Flywheel: It is the one of the main parts of the I.C. engine. Its main function id to store energy in the time of working stroke or expansion stroke. And, it releasesenergy to the crankshaft in the time of suction stroke, compression stroke & exhaust stroke. Because, engine has only one power producing stroke.

How to put the bottle full of drink inside the refrigerator to cool so that it cools

Mechanical engineers know How to put the bottle full of drink inside the refrigerator to cool so that it cools faster : horizontally or vertically...

I am always fascinated by the subject Heat Transfer. There are so many cool facts about heat.
HEAT this is something which give me ecstatic feeling. Read on to know the mind-boggling science
behind answer. Treating the bottle full of drink as a thermodynamic closed system.One can readily see, if the bottle needs to be cooled, it needs to release its energy out to the environment so that it cools And the objective is to do this as quickly as possible Natural convective heat transfer plays substantial role in this phenomenon.Rate of natural convection is different for horizontal cylinder and vertical cylinder because of its dependence on effective height or length. If bottle is kept vertical, the effective length is more and if bottle is kept horizontally then the effective height is less. Hence in later case, heat transfer rate from surrounding to bottle is less.

Ultimately we don’t have to release extra energy and it takes less time to cool otherwise as we cool bottle, it gets heated up at faster rate in case of vertically position so time for cooling increases. Actually time required to cool in the vertical position for the drink bottle (if dimensions of axial length is assumed about 5 times that of the diameter) is 50 % longer than that required when the bottle is kept in horizontal position inside the refrigerator. Chill that drink quickly by placing it horizontally inside the fridge. It is just awesome fact which only MechiezZ know, isn't it ?

11 Habits for effective Teaching

By Carrie Lam , Academic Director, Teacher & Workshop Leader, Canada

I really appreciate teachers who are truly passionate about teaching. The teacher who wants to be an  inspiration to others. The teacher who is happy with his/her job at all times. The teacher that every other child in the school would love to have. The teacher that kids remember for the rest of their lives. Are you that teacher? Read on and learn 11 effective habits of an effective teacher.

1. ENJOYS TEACHING.
Teaching is meant to be a very enjoyable and rewarding career field (although demanding and exhausting at times!). You should only become a teacher if you love children and intend on caring for them with your heart. You cannot expect the kids to have fun if you are not having fun with them! If  you only read the instructions out of a textbook, it's ineffective. Instead, make your lessons come alive by making it as interactive and engaging as possible. Let your passion for teaching shine through each and everyday. Enjoy every teaching moment to the fullest.

2. MAKES A DIFFERENCE.
There is a saying, "With great power, comes great responsibility". As a teacher, you need to be aware and remember the great responsibility that comes with your profession. One of your goals ought to be: Make a difference in their lives. How? Make them feel special, safe and secure when they are in your classroom. Be the positive influence in their lives. Why? You never know what your students went through before entering your classroom on a particular day or what conditions they are going home to after your class. So, just in case they are not getting enough support from home, at least you
will make a difference and provide that to them.

3. SPREADS POSITIVITY.
Bring positive energy into the classroom every single day. You have a beautiful smile so don't forget to flash it as much as possible throughout the day. I know that you face battles of your own in your personal life but once you enter that classroom, you should leave all of it behind before you step foot in the door. Your students deserve more than for you to take your frustration out on them. No matter how you are feeling, how much sleep you've gotten or how frustrated you are, never let that show. Even if you are having a bad day, learn to put on a mask in front of the students and let them think of you as a superhero (it will make your day too)! Be someone who is always positive, happy and smiling. Always remember that positive energy is contagious and it is up to you to spread it. Don't let other people's negativity bring you down with them.

4. GETS PERSONAL.
This is the fun part and absolutely important for being an effective teacher! Get to know your students and their interests so that you can find ways to connect with them. Don't forget to also tell them about yours! Also, it is important to get to know their learning styles so that you can cater to each of them as an individual. In addition, make an effort to get to know their parents as well. Speaking to the parents should not be looked at as an obligation but rather, an honor. In the beginning of the school year, make it known that they can come to you about anything at anytime of the year. In addition, try to get to know your colleagues on a personal level as well. You will be much happier if you can find a strong support network in and outside of school.

5. GIVES 100%.
Whether you are delivering a lesson, writing report cards or offering support to a colleague - give  100%. Do your job for the love of teaching and not because you feel obligated to do it. Do it for self-growth. Do it to inspire others. Do it so that your students will get the most out of what you are teaching them. Give 100% for yourself, students, parents, school and everyone who believes in you. Never give up and try your best - that's all that you can do. (That's what I tell the kids anyway!)

6. STAYS ORGANIZED.
Never fall behind on the marking or filing of students' work. Try your best to be on top of it and not let the pile grow past your head! It will save you a lot of time in the long run. It is also important to keep an organized planner and plan ahead! The likelihood of last minute lesson plans being effective are slim. Lastly, keep a journal handy and jot down your ideas as soon as an inspired idea forms in your mind. Then, make a plan to put those ideas in action.

7. IS OPEN-MINDED.
As a teacher, there are going to be times where you will be observed formally or informally (that's also why you should give 100% at all times). You are constantly being evaluated and criticized by  our boss, teachers, parents and even children. Instead of feeling bitter when somebody has something to say about your teaching, be open-minded when receiving constructive criticism and form a plan of
action. Prove that you are the effective teacher that you want to be. Nobody is perfect and there is always room for improvement. Sometimes, others see what you fail to see.

8. HAS STANDARDS.
Create standards for your students and for yourself. From the beginning, make sure that they know what is acceptable versus what isn't. For example, remind the students how you would like work to be completed. Are you the teacher who wants your students to try their best and hand in their best and
neatest work? Or are you the teacher who couldn't care less? Now remember, you can only expect a lot if you give a lot. As the saying goes, "Practice what you preach".

9. FINDS INSPIRATION.
An effective teacher is one who is creative but that doesn't mean that you have to create everything from scratch! Find inspiration from as many sources as you can. Whether it comes from books, education, Pinterest, YouTube, Facebook, blogs, TpT or what have you, keep finding it!

10. EMBRACES CHANGE.
In life, things don't always go according to plan. This is particularly true when it comes to teaching. Be flexible and go with the flow when change occurs. An effective teacher does not complain about changes when a new principal arrives. They do not feel the need to mention how good they had it at their last school or with their last group of students  compared to their current circumstances. Instead of stressing about change, embrace it with both hands and show that you are capable of hitting every
curve ball that comes your way!

11. CREATES REFLECTIONS.
An effective teacher reflects on their teaching to evolve as a teacher. Think about what went well and what you would do differently next time. You need to remember that we all have "failed" lessons from time to time. Instead of looking at it as a failure, think about it as a lesson and learn from it. As teachers, your education and learning is ongoing. There is always more to learn and know about in order to strengthen your teaching skills. Keep reflecting on your work and educating yourself on what you find are your "weaknesses" as we all have them! The most important part is recognizing them and being able to work on them to improve your teaching skills. There are, indeed, several other habits that make an effective teacher but these are the ones that I find most important. Many other character traits can be tied into these ones as well.

LAST WORD: There is always something positive to be found in every situation but it is up to you to find it. Keep your head up and teach happily for the love of education!

Most study engineering due to parental push:Survey

CHENNAI: Around 65% of students enroll in engineering courses out of parental compulsion and many had got admission despite low scores in physics and maths which are key subjects for engineering to determine aptitude. These are the findings of a study conducted by M-tutor, a private company that develops supplementing tools for educational learning.
The study conducted across nearly 100 colleges in various states found that such students who had enrolled in engineering courses due to parental  compulsion displayed a lack of interest in the field and did not have any long-term career goals. Such students experienced high peer pressure right from day one, it found.
K V Nandita, a telecom engineering student, said that she had initially failed in Maths in her plus-two exam and had to re-appear for the exam before applying for an engineering seat. "My marks were not great but since nearly everyone in my class was taking up engineering, I wanted to get into engineering too," she said. "We observed that in such cases, the parents also put pressure on institutions for placements. This in turn pressurizes the institutions to focus on a quantitative rather than a qualitative approach in their academic processes," said V Sundaramoorthy, managing director of M-tutor.
The study also discerned a change in patterns of learning among students over the last decade. This included their focus being affected due to high levels of distortion because of exposure to digital mediums. The study also found that their ability to grasp concepts during a a classroom session and to take down notes had weakened. Most of them were hesitant to even express this shortcoming to their own classmates, it said.
"Learning dynamics have changed from subjective approach to examination approach. There is a lack of scientific tools to monitor the outcome of the learning imbibed by students and their interest in the concepts," said Sundaramoorthy.

CAD/CAM COURSES

In general, there are three program options for mechanical CAD students, including certificate, diploma and 2-year degree programs. Certificate programs are frequently two semesters in length and designed to train entry-level mechanical CAD operators. There are also certificate programs that require fewer credits to complete, which are designed for students with engineering backgrounds.

Mechanical CAD diploma programs include a few general education courses along with CAD and engineering design courses.  Associate's degrees in mechanical CAD require an average of 70 credits and include general education, mechanical CAD and other technology courses. An Associate in Applied Science in Mechanical CAD is for students who want to become professional mechanical drafters.

List of Courses
The following courses are commonly offered in mechanical CAD educational programs. Beginning CAD Course This foundation course teaches students to operate CAD software and hardware. Traditional technical drafting skills, including freehand sketching, are reviewed. Basic CAD skills are introduced and used to create 2-dimensional representations. Various software packages, including AutoCAD, are also taught.

Mechanical CAD Course
In this course, instructors introduce CAD techniques for mechanical drafting, building on the skills learned in the beginning CAD course. Mechanical CAD students create detailed engineering drawings using CAD software such as ProE. Industry standards for engineering design, including geometric dimensions and tolerance standards, are incorporated in class work. Computer Graphics for Engineering Course Topics covered in this course include creating 3- dimensional graphical representations of mechanisms. Students use applications such as animation software to view engineering graphics. This is an introductory course completed in the first semester of study in a 2-year program. Manufacturing Materials and Processes Course Properties of various manufacturing materials are surveyed in this course. Processes used to engineer products, such as forming and molding, are also covered. Specific materials studied include metals, plastics and ceramics. This course is a prerequisite for a course in machine design.

Machine Design Course
Students study the function of individual machine components and then design each component using
CAD software. Coursework concentrates on material choice, precision calculations and cost estimates. A portion of the course is focused on the inter connectivity of mechanical elements such as
belts, bearings, cams and shafts, in machine design.

Physics and Materials for Mechanical CAD

Operators Course
In this course, students study the physical properties of materials and material performance under certain stressors. General physics topics such as inertia, stress and torque are reviewed. This course is normally completed near the end of a 2-year program. As at the first step I have try to list all the CAD software. If I am missing some software to mention, than surely you can help me by informing me about that CAD, thermal software.

Top 10 Mistakes Done By GATE Aspirants

1. Studied wrong / wrongly. Always prefer standard books. A little mistake can lower your GATE rank.

2. Not properly revised after a certain period of time. “Practice makes man perfect.” Revise what you
have studied time to time.

3. Loosing confidence after seeing the questions paper. Don’t worry question paper is also hard for all
others.

4. Your time management in exam was not so good as you thought. Do solve practice papers time to time with time management same as GATE exam.

5. Never prepared Mathematics and General Aptitude upto that level that I prepared Technical. Don’t forget Mathematics and General Aptitude. These subjects have 30% ratio of total marks.

6. Only prepared previous years papers. Previous years papers will help you to analysis GATE exam but will not sure your golden success. You have to do more study other than previous years papers.

7. Didn’t prepared all subjects because there was no time for those. Always prepare a time table then prepare. Being good in all subjects is always better than being master in only one subject.

8. Don’t feel restless and anxious before examination. Before exam day, take proper rest and food.

9. Fear of examination. Fear is obvious, accept it but don’t focus on it much, don’t let it affect your performance in exam.

10. Forgot Admit card or forgot calculator. It is little but general mistake. It happens because of exam pressure. To avoid this, prepare yourself a day before your exam.

“You need not to be perfect in exam. You need to do well as compare to other in exam.”

Is it necessary to join coaching for GATE 2016 ?

“How do I prepare for GATE 2016 without coaching? What should be my strategy to start preparing for GATE 2016 self ? You all must have this kind of questions in your mind. Below article will solve this puzzle of yours. Just take a look.”

First of all best wishes to whom who did very well in GATE 2015. Who will get good rank in GATE 2015 will surely get good college for higher education and those who want a job with PSU will surely get selected in PSUs but those who don’t get good rank in GATE 2015 don’t lose hope world hasn’t end here.
You have a great  opportunity again to make it possible this time with a very good GATE rank, it is GATE 2016. Start your preparation again this  time with Little more effort, little more concentrate, little more dedication, little more better analysis and little more hours with study. So, candidates who wish to prepare self make a proper plan for rest of the days and stick to that until GATE 2016 examination.
Those who are preparing self they need more  dedication and concentration because you are the mentor of yourself, you are the examiner of yourself. So beside an aspirant, beside a student you are  also playing a role of examiner of yourself.
Candidates who can not join any coaching or don’t want to join any coaching for GATE 2016 preparation must consider these points. If you can get guidance from any of your senior or any of your friend who have cleared GATE previously. If you can arrange some good coaching institute material.
Remember not a single institute is always good in all subjects but you can arrange a single good  study material as per your requirement by choosing from different-different coaching institutes. If you can manage someone who can guide you time to time then no need to join any coaching because coaching is for mainly save your time but many times it waste your time. If you are serious about GATE 2016 preparation and want to utilize your whole time and if you have studied well at your graduation level  then no need to join coaching just sit on chair and start preparation. You may join any or many test series for last time preparation. I have seen many GATE topper who just read standard book and make in GATE top 10 list.
Those who are preparing with any coaching institute they must Consider some points before joining  any online or off line coaching institute. Before choosing any online or offline coaching institute just look into few points as written below which will help you to select a correct institute for your preparation:

1- If we talk about any offline coaching institute then first thing is whether you want to join coaching
in your city or in other city. If you can join coaching out of your city if your family and all other conditions permits than consider all coaching institute which can help you to get good rank in GATE 2016. Living in your own city may help you in basic daily activities like food, cloths, travelling etc. So if you can prepare well at home then you must check any of good coaching institution available in
your city. If there is no any coaching as per your expectations then you can join coaching other than
your home city.

2- First of all get feedback from some students of a particular institute. You can choose as much as institute as much as you want for analyzing. Analyze experience of student about that particular institute, about their study techniques, study material, problem solving and explanation techniques and individually problem solving sessions like many students always can’t ask question is a full strength classes and they get no more benefits from joining any coaching institute it is like wasting your time while sitting in room like waiting room where you wait to end of the class time.

3- Select any coaching for your GATE 2016 preparation on the basis of your requirement and coaching institutes present performance. Do not choose any institute for study on the basis of how big  his coaching institute is famous. Many students go with big name and they got nothing much like
their name so before get admission in any institute for your GATE 2016 preparation choose any coaching institute wisely because after all it is about your career, your whole one year, your dedication and also about your family because many students are there whose family depend on  them or will be dependent very soon. So every decision of you depends upon many factors.

How to prepare for gate 2016 in 6 months ?

By Experts
“How to prepare for gate 2016 in 8/6/3 months ?? You all must have this kind of questions in your mind nowadays. Below article will solve this puzzle of yours. Just take a look.”
I am writing this post on July 2015 from here you have nearly 8 months for preparation of GATE 2016. Here I will tell you how to prepare for GATE in just 6 months or less. You must have heard that some candidate says that I studied for only 6 months or 3 months and get 3 digit rank in GATE. You must have thinking that, that  candidate is awesome. He is surely awesome but have you ever think what he/she did awesome with his/her study? Here I am going to throw light on such key points. I am writing these point keeping in mind that a candidate have just 6 months to prepare for GATE 2016.
Here, First I am writing some points which you must consider first. Don’t start study with reading standard books
You must have thinking that I always suggest you guys that always study using standard books. Here what I just wrote is different I said don’t start with standard books not don’t use standard books. Now I think you are understanding what I want to tell you.
If you start your study for GATE 2016 by reading standard books you would not go so far, just end up by completing a book of a single subject in this whole 6 month period because standard reference books contain 1000-2000 pages with lots of topics and information in it.
The syllabus of GATE is as large as your B E / B Tech complete course. So, Here you are going to complete that 4 year syllabus in just 6 months using lots of books, Guides and MCQ banks. Is it possible in just 6 months ? Think yourself.
You can’t even get all the information contain in a single standard book in these 6 months. So, Here
you have to change your approach.
Then what to do ?
Answer is right below.
First Complete GATE Syllabus Obviously if you are preparing for GATE 2016 you need to complete your whole GATE syllabus in just 6 months or earlier. So, If you start your preparation without any proper approach you will not be able to complete your whole GATE 2016 syllabus in just 6 months. There may be many reason for not being  complete your GATE 2016 syllabus in these 6months like you studied some topics in very deep while they were not much important from exam point of view, you spent lots of time on a single subject like your favorite one, din’t study regularly like study for 2 days all day and night and after that 10 days rest, studied topics which are less or not important from exam point of view.
So, Here your first preference must completing the whole GATE syllabus first. Obviously you have less time so you can’d go in depth of each topic and each subject. So study little bit of everything, little bit of each topic and each subject and finally little bit of the whole syllabus.
Does questions get repeated in GATE ?
This point is also worth considering while preparing for GATE 2016. Many would tell you no GATE
question doesn’t get repeated generally. Here I would like to tell you GATE question also get repeated but in different way. They will not ask the same question again but they will ask the question with same approach again. Like they asked a question, what is 1+1=?. Next time they will not ask the same question in the same way, they will ask like what is 2+3=?. Question may be different, values provided in the question may be different but approach of solving question will be almost same. GATE syllabus is huge to prepare in just 6 months but here is a secret, GATE paper mostly contain numerical problems and numericals are based on formulas and formulas are limited. So, this is a key point by using this you can even limit this GATE huge syllabus by using some techniques. How to prepare for GATE 2016 in 6 months ?
Again this post is specially designed for those candidates who want to prepare for GATE 2016 exam in just 6 months. Candidate preparing for GATE for 1/2/3/4 long years may follow this approach but will not be appropriate for those because they have huge time to prepare instead of just 6 months.

1. Start with previous years papers. Buy a book with previous 20-30 years solved papers. Solve each
and every question precisely. Not just solve but also understand and solve questions which are closely related to that particular question from standard books. Remember solving questions without understanding will not help you much.

2. After solving previous 20-30 years papers nicely you will have a good idea about what kind of questions they ask in exam and from which topic they ask the most or frequently. Now note down such all topics and do solve some more questions from standard books or you may refer some good MCQ books related to those topics. Remember don’t waste your time on hard topics because your every single minute count here. You have limited time just 6 months for GATE 2016 preparation.

3. Now its time to solve some mock tests. Arrange some previous mock tests from your friend or buy any mock test book from market and solve every question of the test precisely. Certainly you would not able to solve all the question of the test. This is not the point where you need to worry. Here you will get a good idea about in which area you are strong and in which area you are weak. Go through each question one by one, to which you were not able to solve. Solve them with the help of standard books, internet etc.. Study enough so that you can answer the similar kind of question next time easily, if it appears. Remember, Here again try to understand the basic of that particular topic not go in depth. We have limited time just 6 months to prepare. If you find a question hard to understand or
unlikely to be asked in exam, skip it. Mark it for later and move on. You can come back to these kind of questions later if time permits.

4. Repeat the same approach. keep solving as many paper as you can. It will increase your level of understand that what kind of question GATE office is going to ask in GATE 2016 exam and this  will also give you an idea that how you would handle such kind of questions in GATE 2016 exam. If   possible join some online test series of some reputed coaching institutes. It would be better to join multiple institutes test series if you can because you will face variety of question from different- different institutes. You will face different-different kind of questions for the same subject designed by different-different institutes master. It will also help you in you real time GATE 2016 exam because GATE exam is nowadays online computer based test(CBT).

5. Last but very important point besides understanding lots of things, reading lots of stuff, referring lots of books, joining lots of test series you need to remember these all things atleast till the GATE 2016 exam finish. So need to revise these all things time to time so always prepare a plan or time table which contain timely revision. Make a time table for a whole day, for a week, for a month and for next 6 months for GATE 2016. Stick to the time able. Must include time for revision in each time
table.
Summary
Do’s
1. Start preparation by solving previous 20-30 years papers. It will give you a good idea about what you have to prepare and what not to prepare. Because in this competitive world you need to be smart along with having knowledge.
2. First complete GATE whole syllabus as soon as possible. You are going to attend GATE 2016. So, You have to complete it completely before GATE 2016 examination. Examiner may ask question from any subject and also from any topic mentioned in GATE 2016 syllabus.
3. Solve previous 20-30 years papers precisely. Don’t just solve them, understand them. GATE question don’t get repeated but by solving previous years papers you are being familiarize with questions asked in GATE exam. So that you can prepare according to that now for GATE 2016.
4. Solve question which are closely related to previously asked questions. GATE question don’t get repeated but approach may get repeated. So solving related questions will surely increase your marks in GATE 2016 exam.
5. Join some good online mock tests and prepare for them nicely. As nowadays GATE exam is an online computer based test (CBT). So these online mock tests will prepare you to be familiarize with exam like environment and will also help you to improve your GATE 2016 preparation.
6. Make a proper time table as per your daily routine for a day, a week, a month and for 6 month period and stick to that. As you have less time to prepare, So you need a proper plan to complete your whole GATE 2016 syllabus within time limit of 6 months.
7. Always keep a place for revision in your time table. Revision is really-really important because you can’t remember all the things you have studied in last 6 months.
must check : PSUs through GATE 2016

Don’ts
1. Don’t start preparation by reading standard books. As you have less time to prepare, So you need be more focus on what you have to study first and what later. Its all about time management when
time is less.
2. Don’t just solve previous years papers. Just solving previous years papers will not help you much in GATE 2016 exam. It will even confuse you more in exam. So, solve previous years papers with understanding not just solving. 
3. Never go in depth of some topics or subjects. Obviously examiner is not going to ask all the question from the subjects which you have prepared well. They will ask question from almost all subjects. So prepare all subjects equally first.

“GATE examination is to check basic knowledge and understanding of a candidate at their graduate
level.”

Motivate yourself for Gate or future!

By Expert..

1. If you show some guts to open up by not hiding behind "anon" - may be some one would have noted your situation and might have assisted you.

2. The moment you don't get a job, you people feel that you are untouchable. If that is what you believe how outsiders can understand you?

3. You are just 23- ( believe me if you can) when I was 45, a mere commerce graduate had two
children - I left the job to move back to my state - but without a job for 1 year. Then I just invented myself - and changed not only the horses but also the entire vehicle - and migrated from accounts to advertising.

4. You have not got GATE, and you are an instrumentation engineer and you got a break in employment and you feel and decided that you have
been fucked up.

5. Did you ever do masturbation? After doing it, did you ever feel guilty of doing it? And after a week you did it and enjoyed it and after its over you feel guilty about it ... it's a unending story.

6. I am afraid you young people should learn lot from Congress party. You can not be a AAP member and still want to survive in this society.

7. There are no Sages or Sri Rama in this society and we are all in a kind of society where we make up ourselves to get our daily bread.

8. The HR manager is cheating telling you in his company - only the real worker will be rewarded;
The management cheating explaining that the sky is the limit for real performer.
The Banker is cheating that they have money to loan you;
The team manager is cheating by telling that all the team members are equal to him. And we - as an individual - are unable to tell simple lie for our own life sake.

We tell lies to our girl friends and to our parents but when it comes to the job, we want to be naked there.

9. Stop telling in resume that you have a break ( not GAP) in employment. So after two days you will believe in your resume. You search some thing - some idea, some clue to cement that "gap". And re write the resume.

10. Do not show your or explain your strengths and weakness etc., Add a good convincing creative covering letter.

11. Being instrumentation engineer - you should look for job titles like " Team manager, assist manager - commercial, or purchase or design or Site Engineer of any trade, or else get back to e commerce ( not a software job)

12. Don't get fucked up by drawing circles and boundaries around you.

13. Have some flexibility and look beyond that instrumentation and GATE.

14. There are half a billion people with out IIT or IIM
or GATE. And they are happy.

15. Do not spend too much time on FB, delete your resume from Linked In.

How to study smart not hard?

Why is it that some students study really hard, but aren’t the best in their age group or get “only” average grades? And why is it that there are other students who do not even invest half the amount of time and effort into their studies, but get good or even outstanding results?

Intelligence certainly plays a role. But: The way you study can make or break your success at school/
college/university. My recommendation is to study smart, which can help you to save a lot of time  that would have been lost with unfocused attempts of “studying hard”. This article is, however, not intended as an excuse for students not to study at all. You will have to invest the proper amount of time for studying, there’s no way around. But, this article guides you on how to make the most out of the time you invest for studying. This article’s goal is to enable you to reduce the unnecessary parts of your studies and to focus on the important.
When I started studying, I was shocked to see many of my fellow students rushing into the library only to leave with seven or more books in their hands. That’s what I call ambitious. Many of them had lent every single book our professor’s had commended – sometimes up to 4 different books per  subject. Inclusively the script for each subject, it became a massive mountain of learning material (for them). For a very short time, I was a little frightened by their eagerness, but I held on to the decision of keeping my focus on the important. I kept it simple, lent two books I really needed, and in the end – I got the same and often better results in the examinations than the “overachiever”-crowd.

How did I do it? I studied smart and only periodically hard.
How to study smart not hard?
And how to avoid studying for so long?
This article is partitioned into three parts. 

Part A) Preparation and
Part B) Mindset focus on the organization of information that makes it easier for you to recall.
Part C) is the main part of the concept of “studying smart”.

A) Preparation

1. Get a study game plan.

You want to study smart, right? Hence, it makes sense not to approach your work in an unfocused, undirected way. Don’t dive head first into the topic. That’s the way that would actually cost you a lot of time. Instead, create a study game plan where you specify the day you begin to prepare for your exams create a daily schedule of tasks you want to accomplish during exam preparation create a detailed to-do-list , (keep a close eye on what is really important) enumerate the books you need to read (better: just the important sections you really need to know for the test) itemize the various tasks and exercises you want to do for preparation.
Depending on the difficulty of your exams and how many weeks and months you have for studying,
you could also categorize the weeks/months for preparation into different phases, from
I. basic refreshment of knowledge ,
II. studying, revision and exercise to
III. intensive cracking down – social life on hold.
How to do it the smart way?
A clear goal that you pursue gradually with your plan helps you to avoid many extra- hours, but it also allows you to direct your focus on the important.

2. Summarize.

I’ve had many exams about the content of an entire  book, most of these books in the range of 500-1200 pages. And even if you have only some chapters from a book/journal to read for the test, I highly  recommend you to create summaries, while working through the book. That way, you establish the fundament on which you can build upon, during the upcoming study phase, without having to read the book all over again. But you also train yourself to quickly identify the key statements in large texts that are very likely to be tested in the exam. As a consequence, it’ll be easier for you to skip large amounts of irrelevant data, while sifting through the book.

3.Separate the wheat from the chaff.

While you listen to a lecture or read through a textbook, give the  following a try:

Separate  continuously information that is important (“ Could this knowledge be tested in an exam? ”) from the unimportant (“ Is my teacher digressing or listing irrelevant data? ”).
Take notes of the important points your professor/teacher talks about and add annotations to your script or lecture notes.  Making these important additions to your script will help you at a later time to grasp important coherences.  You can also highlight important sentences or passages from the text, so that you can easily avoid reading through large amounts of unimportant data in your script.

B) Mindset

1. When you study, give 110%

When I went to school, I almost always had to study for long periods of time in order to memorize and understand given contents. The big mistake I made  was to study hard and for long periods of time, but I was not always focused on what I did. I got distracted by my mobile phone, the internet, TV, radio, telephone, friends or any other amusement one can think of. Nowadays, when I study I always give a 110%; I reduce distractions to a minimum and give my very best to avoid procrastination. I may have a time limit of 1-2 hours, but I want to make use of that time as much as possible. Thereafter, I have even more leisure time.
How to study smart:
When you study, do it in a focused and proper way, avoid any kinds of distractions and use the time you have to the maximum!

2. Continuity

Doing all-nighters some days before your examinations will not only exhaust you to a large degree, but will also force you to rush through the data, in place of studying properly. Instead of opting for all-nighters, consider spending half an hour after each day at university with post-treatment, i.e. reading a chapter in the book, making a summary  or doing some exercises. All this preliminary work will help you to spend more time with studying (during your exam preparation period), instead of having to engage with all kinds of inefficient tasks, such as extracting data from your books, trying to
grasps (arithmetic) operations and building an understanding etc.
Why is that smart?
If you already did the groundwork during the term, you’ll be able to focus a lot more on smart ways of studying.

C) The main part of “ studying smart”

1. Don’t try to memorize, understand!

One of the major mistakes I made – when studying hard not smart – was to learn by heart, which is really time-intensive. Rote memorization is fine and dandy if an upcoming exam requires you to reproduce what you have learned word for word. But the higher you rise in the educational system, the less important will it be to memorize and  reproduce, as your understanding and the ability to draw consequences will be tested instead.
In most cases, memorization corresponds to studying hard, not smart. Focus your attention on the understanding and comprehension of the knowledge that is taught.
But: How to understand complex topics?

Establish links and associations
Information becomes knowledge through connections. If you cannot relate to a complex topic, it’ll be very difficult to understand it. But, when you discover similarities and link new knowledge with concepts that you already comprehend, understanding the matter becomes easier. Try to spot ties between different topics and establish links between concepts that overlap.
Studying smart can help you to save a lot of time Imagine the subject matter as vivid as possible. Instead of recognizing the fact that the material you study consists of numbers, words and sentences,
think in pictures (headword: visually thinking). By doing so, you direct a movie in your mind that will help you to memorize facts faster and for a longer period.
What you basically do is the association of emotions (in the form of pictures) with rather unemotional data. It is difficult to memorize the numbers “483215”, but if you link each number with a picture and create a funny story out of it, it will be very easy to memorize the number-combination for a longer period of time. [By the way, this is THE memory trick artists use to memorize seemingly- indefinite number combinations.]
Emotions
Connecting emotions with your subject will greatly help you to internalize the topic. Have fun while studying! It’s for a fact that remembering things we  associate intensive feelings with is by far easier.
Also, if you’re really interested in a subject matter, learning becomes a lot more joyous. Once you manage to become curious about your subject and develop an interest in it, you’ve made an important
step towards a smarter way of studying.
Simplification through analogies
In school and university you’ll be confronted with various complex facts and circumstances. Make
use of analogies [= comparisons] and try to compare a very complicated issue with a more simplified one, which makes it easier to understand the bigger picture of that which is taught.
Simplification through patterning
While you study, make sure to pay attention to continual patterns within the subject matter that occur again and again. By noticing and understanding these reoccurring patterns, you begin to understand the framework on which the topic is constructed. Once you have a good overview of such a framework, the acquisition of new information that is based on the same pattern will be a lot less difficult.
Make use of acronyms
If you’re confronted with difficult, specialist words,  names or formula, an acronym can be an excellent aide-memoir for the memorization of the word or formula. Take for instance the rather simplex name “Enhanced Health and Usage Diagnostic System”. It’s acronym is “EHUDS”, which sounds like “e- hud’s” or “e-hat’s”. All you have to do now is to think about electronic hat’s and you’ll most likely be able to come up with the acronym “EHUDS”, from which you can rebuilt the original name.

2. Keep the bigger picture in mind

The constructing of a car can serve as example of the learning process. Your professor supplies the “know how” during his lectures, for instance the  detailed knowledge how an engine works. The textbooks and other learning materials supply you with the chassis, frame, tires and bolts. But, it is up to the student to make use of the know how, in order to use it for the combination of the delivered material. It’s the student’s job to put the car together and to keep the bigger picture of what is taught in mind.
If the student stubbornly tries to memorize the position of each part in the car, he/she will not be able to (re-)construct a car from a thousand of individual parts. Memorizing the different names of each part will not help either.
Only by keeping in mind that the know how and material are at one’s disposal for the creation of a
car, the student can effectively prepare for an upcoming test.

3. Perfect your type of studying

There are basically four basic types of studying: Visual, Auditory, Emotional and Kinesthetic.

1. Visual Learners: A visual learner studies most effective when the learning material is depicted in a visual way, e.g. in the form of charts, maps or brainstorming.
2. Auditory Learners: An auditory learner studies most effectively by hearing the information, for instance in a lecture or by recording their own words.
3. Emotional Learners: An emotional learner studies most effectively by associating feelings, emotions and vivid images with the information.
4. Kinesthetic Learners: A kinesthetic learner studies most effective when the information can be experienced and felt, i.e. via “learning by doing”.

Effective Study Methods
In order to study in the smartest possible way you need to discover which type of studying you prefer.
Once you know what works best for you, align your process of learning to make the most out of it.
Students that are mathematically talented should put their notes into spreadsheets, graphs and charts; kinesthetic learners imagine the learning material as vivid as possible; linguistic learners discuss the material with others or record their voice while reading the subject out-loud, etc.
