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 change Will remain same Will not occur Could change or remain unaltered depending on which link is fixed Will change Will remain same Will not occur Could change or remain unaltered depending on which link is fixed ANSWER DOWNLOAD EXAMIANS APP
