Question

Which of the following motion has the maximum number of infinite jerks in one rotation of the cam shaft?

(a) Simple harmonic

(b) Uniform acceleration

(c) Uniform velocity

(d) Uniform acceleration and retardation

This question was addressed to me during an online interview.

I would like to ask this question from Velocity and Acceleration Diagrams in portion Cams of Machine Dynamics

Answer 1

The correct option is (b) Uniform acceleration

The best I can explain: Uniform velocity motion is proved to be useless for practical purposes as there are infinite inertia force results due to many number of infinite jerks between the motion, so from the given options it is observed from the graph that uniform velocity motion has maximum number of jerks in one rotation of the cam shaft.
