Question

From the given figure below, at what value of theta(angle of ascent) the acceleration will be maximum?

(a) 0

(b) 30

(c) 60

(d) Constant acceleration

This question was posed to me during an internship interview.

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

Answer 1

Correct option is (d) Constant acceleration

The explanation is: The given figure is the displacement diagram of the follower undergoing a constant acceleration and retardation motion, thus as a result of that there is a constant value of acceleration and has no maxima and minima.
