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