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 acceleration and retardation

The question was posed to me in unit test.

My query is from Velocity and Acceleration Diagrams topic in chapter Cams of Machine Dynamics

Answer 1

Right answer is (d) Uniform acceleration and retardation

Explanation: The given figure is the velocity time diagram of the uniform acceleration and retardation motion of the follower with initial dwell. This is a linear curve as the velocity relation changes linearly with time.
