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 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 Will remain same ANSWER DOWNLOAD EXAMIANS APP
