Theory of Machine Flexible coupling is used because It is easy to engage and disengage It prevents shock transmission and eliminates stress reversals It is easy to disassemble It transmits shocks gradually It is easy to engage and disengage It prevents shock transmission and eliminates stress reversals It is easy to disassemble It transmits shocks gradually ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a steam engine, one method of obtaining the earlier cut-off with a simple slide valve is by increasing the angle of advance of the eccentric while the throw of the eccentric, steam lap and exhaust lap are kept constant. This method will All of these Reduce maximum opening of port to steam Reduce length of effective stroke of piston Cause withdrawing or throttling of steam All of these Reduce maximum opening of port to steam Reduce length of effective stroke of piston Cause withdrawing or throttling of steam ANSWER DOWNLOAD EXAMIANS APP

Theory of Machine Which is the false statement about the properties of instantaneous center? The two rigid links have no linear velocities relative to each other at the instantaneous center 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 At the instantaneous center of rotation, one rigid link rotates instantaneously relative to another for the configuration of mechanism considered The two rigid links have no linear velocities relative to each other at the instantaneous center 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 At the instantaneous center of rotation, one rigid link rotates instantaneously relative to another for the configuration of mechanism considered ANSWER DOWNLOAD EXAMIANS APP
