Planar mechanisms are _ dimensional whereas spatial mechanisms are _ dimensional.

A

1, 2

B

2, 1

C

2, 3

D

3, 2

Correct Answer: 2, 3

Planar mechanisms are restricted in a single plane and spatial mechanisms have no such restriction. The relative motion between particles in a spatial mechanism is not in the same or parallel planes. Thus, planar mechanisms are 2 dimensional whereas spatial mechanisms are 3 dimensional.

Planar mechanisms and spherical mechanisms are included under spatial mechanisms. True or false?

A

True

B

False

3. Section 149 requires five or more persons whereas section 34 requires two or more persons.
