Theory of Machine Angle of action of cam is defined as the angle Through which the cam rotates during the period in which the follower remains in the highest position Of rotation of the cam for a definite displacement of the follower Moved by the cam from beginning of ascent to the termination of descent Moved by the cam from the instant the follower begins to rise, till it reaches its highest position Through which the cam rotates during the period in which the follower remains in the highest position Of rotation of the cam for a definite displacement of the follower Moved by the cam from beginning of ascent to the termination of descent Moved by the cam from the instant the follower begins to rise, till it reaches its highest position ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a mechanism, usually one link is fixed. If the fixed link is changed in a kinematic chain, then relative motion of other links Could change or remain unaltered depending on which link is fixed Will change Will not occur Will remain same Could change or remain unaltered depending on which link is fixed Will change Will not occur Will remain same ANSWER DOWNLOAD EXAMIANS APP
