8.Angle of ascent of cam is defined as the angle |
| during which the follower returns to its initial position |
| of rotation of the cam for a definite displacement of the follower |
| through which the cam rotates during the period in which the follower remains in highest position |
| moved by the cam from the instant the follower begins to rise, till it reaches its highest position |
