Question

With respect to the figure given quadrilateral CQNO is known as _______

(a) Klein’s acceleration diagram

(b) Klein’s velocity diagram

(c) Klein’s displacement diagram

(d) Bennet’s diagram

I have been asked this question by my college professor while I was bunking the class.

This interesting question is from Klien’s Construction topic in chapter Inertia Forces in Reciprocating Parts of Machine Dynamics

Answer 1

The correct choice is (a) Klein’s acceleration diagram

To explain I would say: Ar(co) is parallel to CO, Ar(cp) is parallel to CP, At(pc) is parallel to QN and Apo is parallel to PO thus quadrilateral CQNO is the acceleration polygon.
