Match the following with respect to spatial mechanisms.
Type of Joint Degrees of constraint P. Revolute 1. Three Q. Cylindrical 2. Five R. Spherical 3. Four wire 4. Two 5. Zero
-
- P-1 Q-3 R-1
- P-5 Q-4 R-3
- P-2 Q-3 R-1
- P-4 Q-5 R-3
Correct Option: C
For revolute joint, degree of freedom = 1
For cylinderical joing, degree of freedom = 2
For spherical joint, degree of freedom = 3
Degree of constraints = 6 – Degree of freedom
