Theory of Machine Angle of descent of cam is defined as the angle Of rotation of the cam for a definite displacement of the follower 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 During which the follower returns to its initial position Of rotation of the cam for a definite displacement of the follower 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 During which the follower returns to its initial position ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The relation l = (2/3).(j + 2) apply only to kinematic chains in which lower pairs are used. This may be used to kinematic chains in which higher pairs are used, but each higher pair may be taken as equivalent to Two lower pairs and one additional link Any one of these One lower pair and two additional links Two lower pairs and two additional links Two lower pairs and one additional link Any one of these One lower pair and two additional links Two lower pairs and two additional links ANSWER DOWNLOAD EXAMIANS APP
