Q:

Match list I with list II

Type of joint Motion constrained
A. Revolute 1. Three
B. Cylindrical 2. Five
C. Spherical 3. Four
4. Two
5. Zero

A) A-1,B-3,C-2 B) A-5,B-4,C-3
C) A-2,B-3,C-1 D) A-4,B-5,C-3
 
Answer & Explanation Answer: C) A-2,B-3,C-1

Explanation: For revolute pair, degree of freedom = 1 and constrained
DOF = 6 – 1 = 5
For cylindrical pair, dof =2 and constrained dof = 6 – 2 = 4
For spherical pair, dof = 3 and constrained dof = 6 – 3 = 3.
