Question

According to criterion of constraint by A.W. Klein

(a) J + 1/2 H = 3/2L – 2

(b) H + 1/2J = 2/3L – 2

(c) J + 1/2H = 3/2L – 1

(d) J + 3/2H = 1/2L – 2

The question was posed to me in examination.

This intriguing question comes from Application of Kutzbach Criterion to Plane Mechanisms in portion Simple Mechanisms of Machine Kinematics

Answer 1

The correct choice is (a) J + 1/2 H = 3/2L – 2

Explanation: The criterion for a chain to be constrained is

J + 1/2 H = 3/2L – 2
