BHEL(ET) PREVIOUS EXAM PAPER for Mechanical
The entire test paper consisted of 240 questions with 5 options for each question and -1/5 marks for wrong answer with 1 mark for right answer.
The paper consisted of primarily four sections
1) Technical Engg (60 Questions)
2) Basic Engg (60 Questions)
3) Verbal Ability (60 Questions)
4) Quantatitive (60 Questions)
A) Technical Engineering (Mechanical)
For Mechanical Engineers only (prod.,manuf.,indust. etc.)
For those who really want to make a difference in this exam in very short term preparation this will be the page that will help you the most.
(Paper pattern etc. (Go through BHEL web site)(120 Techncial(60 Mechanical(10-15 Thermal, 5-10 design, 20-25 production technology, 15-20 Strength and design, 10- no idea); 30- 12th class; 20-electrical); 120 non technical (Very easy but at the same time very much time taking)
Method 1: Practice, practice, practice,. Till die (I have seen these superman in here during training)
Method 2: (My way)
1. RK JAIN theory memorize all theory (leave some which you think you can not handle)
2. Try to search basic of every topic of mechanical from net / wiki go through it.
3. Do not leave any section as a whole from mechanical questions will be very simple from all basics of engineering (except 1 or 2)
4. Quantitative. will be very lengthy in 2 hours you will be able to do only 100-120 you need to grasp all mechanical because the questions from this section can be solved in very short time like 75 in 60 mins (or exceptional data: 95 in 75 min)
5. Use your time like
Mechanical - 1.25hr to 1.5 hour
Non Technical - 1.5 hr to 1.75 hour
Ultimately the decision of selection will be on technical because everyone will be able to solve non technical (Difference will as low as 5 to 10 problems between two persons in non tech) in technical the difference will be 30 to 40 problems between two guys so do not leave technical.
240 questions 150 mins.
Questions in English & Hindi.
240 questions, first 120 technical.
Mainly from heat and mass transfer problems.
* Thermodynamics.
* Panks energy equation.
* Column equation.
In Technical concentrate on HT, SM, DMM, TD, PROD.
Aptitude: concentrate more on surface area, volume. One question from Simple Interest, Boats and streams.
Verbal & Non Verbal: Correction of sentences, analogy, puzzle test.
General Engineering: Major part from Basic Electric Engineering; CS-2 questions, Engg Maths: 3 to 4 Questions.
Then some electronics questions half adder full adder etc.
Some electrical circuit questions.
Some questions from DBMS, computer basics.
Technical section mainly problems.
Problems wil be easy for prepared students.
Some questions couldn't answer without calculator.
They provided those questions to waste our time.
No general knowledge questions.
English aptitude.
Spot the error.
Select the opposite words.
Spelling mistake check.
2 paragraph comprhnsn. (3+3) 6 questions.
Mathematics aptitude.
Find rank of matrix
Find eigon vector.
Ven diagrams.
1 question from sets.
Area of circle, rectangle square type problems(simple).
Basic trignometry.
Simple interest.
Eg: Find the value of 1032 - 532.
Last 60 questions very very very easy.
8th standard students can solve those questions.
But the problem was most of the students waste their time infront of technical problems.
So start answering from last section.
