Question

For a follower Simple Harmonic Motion having a small period of dwell at the beginning of motion, the jerk is 0.

(a) True

(b) False

I have been asked this question in an internship interview.

My question is taken from Velocity and Acceleration Diagrams topic in portion Cams of Machine Dynamics

Answer 1

The correct answer is (b) False

The best I can explain: For a follower undergoing simple harmonic motion, starting off with a small dwell period, when it begins to ascend the acceleration is suddenly increased to a great amount from 0, hence the jerk is also infinite.
