Question

In a kinematic chain, a quaternary joint is equivalent to

(a) one binary joint

(b) two binary joints

(c) three binary joints

(d) four binary joints

This question was posed to me in unit test.

I want to ask this question from Kinematic Chain in chapter Simple Mechanisms of Machine Kinematics

Answer 1

The correct choice is (c) three binary joints

Explanation: When four links are joined at the same connection, the joint is called a quaternary joint. It is equivalent to three binary joints.
