section one

These are the questions which are asked in technical section .
In total there were 46 questions and the given was 30 minutes.
Somebody was saying that they have given the last year paper.
After the questions i am giving the options (the order of questions and as wel as options
May not be the same)

1 in diesel engine the comp. Ratio is ______ then expansion ratio(more,equal,less,...)

2 carbon help in the improving __ of steel(ductility,malliability,hardness,machinability)

3 max hardness in steel is due to
A carbon b sulpher & phosphorus c alloy metal d none

4 ci is used in heavy m/c beds due to(low cost,has high damping coefficient,its easier)

5 spring in series,give relation for stiffness(ans:k1*k2/(k1+k2)

Ans b.

29]there are six cylinder in line rotary engine.how many cranks does this engine has.

section 2

this section contains very logical questions based on gears,pulley and liquid pressure.

Total 60 questions time allotted is 40 min this section contains many figures and questions

Are asked based on those figures.for example

1]7 or 8 gears or wheels are connected either directly or through belt drives.the direction
of motion of one gear is specified.and asked which all other gear will rotate in the same direction.

It is not possible for to give figures for these questions.this whole section contains
at least 10 questions of this type.

2]10 questions are based on weight lifting arrangements like lever,cylider wrapped with a rope
Operated through hand crank,3-4 pulley arrangements,the mechanism used to lift the engines of

cars.you have to find out in which mechanism least strengthis needed.

3]8-10 questions were based on liquid pressure.4 jars are full of water up to the same height.
These jars are provided with tubing of different length and shape and asked in which figure
We will have highest pressure at the end of the tube.

4]one question was : in a centrifuge water oil and merquery is poured and rotated.then which
Liquid will be at the centerand which one will be at the periferi.

5]one question was :a man is standing on a stand generally used by electrician ( /\ type) at
different positions and different height and drilling a hole in the wall.in which case he is

likely to fall.

6]there are 5 shapes for a dam

1 >
2 <
3 )
4 (
5 |
6
Which will be the safest.

7]two or three questions were asked on balancing of masses.like one weight is hung on one side
of a lever then what will be the weight of balancing one.

Section 3

This section is of figurative apptitude.
In a 3 by 3 matrix only the last box is empty.
Figures of each row has some relation among them.so you have to find the missing figure
From 7 options.

This sections cotntains 36 such questions . It won take more than 15 minutes to solve upto 20.
But then it becomes somewhat tougher.the total time alotted is 40 min.

There is a book called "how to face interviews".this book contains the same type of questions.
