Theory of Machine The retardation of a flat faced follower when it has contact at the apex of the nose of a circular arc cam, is given by (where OQ = Distance between the centre of circular flank and centre of nose) ω² × OQ ω² × OQ sinθ ω² × OQ tanθ ω² × OQ cosθ ω² × OQ ω² × OQ sinθ ω² × OQ tanθ ω² × OQ cosθ 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 Will remain same Will change Will not occur Could change or remain unaltered depending on which link is fixed Will remain same Will change Will not occur Could change or remain unaltered depending on which link is fixed ANSWER DOWNLOAD EXAMIANS APP
