Angle of ascent of cam is defined as the angle

A during which the follower returns to its initial position
B of rotation of the cam for a definite displacement of the follower
C through which the cam rotates during the period in which the follower remains in highest position
D moved by the cam from the instant the follower begins to rise, till it reaches its highest position

Correct Answer: moved by the cam from the instant the follower begins to rise, till it reaches its highest position

Angle of ascent of cam is defined as the angle moved by the cam from the instant the follower begins to rise, till it reaches its highest position. Angle of action of cam is defined as the angle moved by the cam from beginning of ascent to the termination of descent.
