Question

The given figure is a velocity time diagram for which of the follower motion?

(a) Simple harmonic

(b) Uniform acceleration

(c) Uniform velocity

(d) Uniform retardation

The question was posed to me during an internship interview.

The doubt is from Velocity and Acceleration Diagrams in chapter Cams of Machine Dynamics

Answer 1

Right choice is (a) Simple harmonic

To elaborate: The given figure is the velocity time diagram of the simple harmonic motion of the follower.

This is similar to the sine curve as the velocity relation is a sine function.
