Theory of Machine The Kutzbach criterion for determining the number of degrees of freedom (n) is (where l = number of links, j = number of joints and h = number of higher pairs) n = 3(l - 1) - 3j - h n = 2(l - 1) - 3j - h n = 2(l - 1) - 2j - h n = 3(l - 1) - 2j - h n = 3(l - 1) - 3j - h n = 2(l - 1) - 3j - h n = 2(l - 1) - 2j - h n = 3(l - 1) - 2j - h ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine Angle of dwell 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 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 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 definite displacement of the follower ANSWER DOWNLOAD EXAMIANS APP
