Question

which motion type do a joint allow each flange of the hinge shown to rotate on its inside cylinder without moving vertically?
a. revolute
b. slider
c. weld
d. cylindrical

Explanation:

A revolute joint allows for rotation about a single axis. A slider joint allows linear motion. A rigid - joint does not allow relative motion. A cylindrical joint allows both rotation about an axis and linear motion along that axis. The hinge shown needs only rotation without vertical movement, which is characteristic of a revolute joint.

Answer:

A. Revolute
