which motion type do a joint allow each flange of the hinge shown to rotate on its inside cylinder without moving vertically?\na. revolute\nb. slider\nc. weld\nd. cylindrical
Answer
Brief Explanations:
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
