MECHANICAL ENGINEERING JOB INTERVIEW QUESTIONS

MECHANICAL ENGINEERING JOB INTERVIEW QUESTIONS:-

1.)What is the difference between plane and spatial mechanism?

Ans: In plane mechanism all the links lie in the same plane whereas in spatial mechanism links lie in different planes.

2.)How many degrees of freedom are there in a constrained mechanism ?

Ans: One.

3.)What is the condition for correct gearing ?

Ans: According to condition of correct gearing, the common normal to the pitch surface should cut the line joining the centers at a fixed point.

4.)Differential between main function of flywheel and governor.

Ans: The function of flywheel is to reduce fluctuation of speed during a cycle and the function of governor is to control the mean speed over a period for output load variations. Flywheel has no influence on mean speed of prime mover and governor has no influence over cyclic speed fluctuation.
