Question

The direction of velocity is parallel if the rotation is anticlockwise and perpendicular to the line joining links if the rotation is clockwise.

(a) True

(b) False

I had been asked this question in class test.

I want to ask this question from Motion of a Link topic in section Velocity in Mechanisms of Machine Kinematics

Answer 1

Right option is (b) False

Explanation: Velocity of any point on a link with respect to another point on the same link is always in the direction perpendicular to the line joining these points on the space diagram both during anticlockwise and clockwise rotations.
