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