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 Could change or remain unaltered depending on which link is fixed Will not occur Will remain same Will change Could change or remain unaltered depending on which link is fixed Will not occur Will remain same ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A system in dynamic balance implies that There is no critical speed in the system There will absolutely no wear of bearings The system is also statically balanced The system is critically damped There is no critical speed in the system There will absolutely no wear of bearings The system is also statically balanced The system is critically damped ANSWER DOWNLOAD EXAMIANS APP
