When a point at the end of a link moves with constant angular velocity, its acceleration will have

A radial component only
B tangential component only
C coriolis component only
D radial and tangential components both

Correct Answer: radial component only

The centripetal or radial component, is perpendicular to the velocity of the particle at the given instant. The tangential component, is parallel to the velocity of the particle at the given instant.
