Question

In the given figure, the velocity of piston is maximum under which of the following conditions?

(a) N lies to the left of O

(b) N lies to the right of O

(c) N coincides with O

(d) N lies above O

I have been asked this question during an interview for a job.

I'd like to ask this question from Klien’s Construction topic in chapter Inertia Forces in Reciprocating Parts of Machine Dynamics

Answer 1

The correct answer is (c) N coincides with O

Easiest explanation: When the crank and the connecting rod are perpendicular to each other, at that instance the acceleration is 0 but the velocity is maximum.
