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
Theory of Machine In a disc clutch, if there are n₁ number of discs on the driving shaft and n₂ number of discs on the driven shaft, then the number of pairs of contact surfaces will be n₁ + n₂ + 1 n₁ + n₂ - 1 n₁ + n₂ - 2 n₁ + n₂ n₁ + n₂ + 1 n₁ + n₂ - 1 n₁ + n₂ - 2 n₁ + n₂ ANSWER DOWNLOAD EXAMIANS APP

Theory of Machine Which is the false statement about the properties of instantaneous center? The two rigid links which have no linear velocity relative to each other at this center have the same linear velocity to the third rigid link The two rigid links have no linear velocities relative to each other at the instantaneous center At the instantaneous center of rotation, one rigid link rotates instantaneously relative to another for the configuration of mechanism considered The double center can be denoted either by O2 or O12, but proper selection should be made The two rigid links which have no linear velocity relative to each other at this center have the same linear velocity to the third rigid link The two rigid links have no linear velocities relative to each other at the instantaneous center At the instantaneous center of rotation, one rigid link rotates instantaneously relative to another for the configuration of mechanism considered The double center can be denoted either by O2 or O12, but proper selection should be made ANSWER DOWNLOAD EXAMIANS APP
