Theory of Machine Angle of dwell of cam is defined as the angle Through which the cam rotates during the period in which the follower remains in the highest position Moved by the cam from the instant the follower begins to rise, till it reaches its highest position Of rotation of the cam for definite displacement of the follower During which the follower returns to its initial position Through which the cam rotates during the period in which the follower remains in the highest position Moved by the cam from the instant the follower begins to rise, till it reaches its highest position Of rotation of the cam for definite displacement of the follower During which the follower returns to its initial position ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The Grubler's criterion for determining the degrees of freedom (n) of a mechanism having plane motion is (where l = Number of links, and j = Number of binary joints) n = 3(l - 1) - 2j n = (l -1) - j n = 2(l - 1) - 2j n = 4(l - 1) - 3j n = 3(l - 1) - 2j n = (l -1) - j n = 2(l - 1) - 2j n = 4(l - 1) - 3j ANSWER DOWNLOAD EXAMIANS APP
