Theory of Machine Which is the false statement about the properties of 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 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 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A spring controlled governor is said to be isochronous when the controlling force Decreases as the radius of rotation increases Remain constant for all radii of rotation Increases as the radius of rotation decreases Increases as the radius of rotation increases Decreases as the radius of rotation increases Remain constant for all radii of rotation Increases as the radius of rotation decreases Increases as the radius of rotation increases ANSWER DOWNLOAD EXAMIANS APP
