(b) varies between v/2 and -v/2

(c) varies between 3 v/2 and -v/2

(d) does not vary and is equal to v

The question was posed to me by my college director while I was bunking the class.

I want to ask this question from Inversions of Four Bar Chain topic in chapter Simple Mechanisms of Machine Kinematics

Answer 1

Right answer is (b) varies between v/2 and -v/2

To explain I would say: None
