Theory of Machine The moment on the pulley which produces rotation is called Momentum Moment of momentum Torque Inertia Momentum Moment of momentum Torque Inertia ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The static balancing is satisfactory for low speed rotors but with increasing speeds, dynamic balancing becomes necessary. This is because, the Unbalanced forces are not dangerous at higher speeds Effects of unbalances are proportional to the square of the speed Effects of unbalances are directly proportional to the speed Unbalanced couples are caused only at higher speeds Unbalanced forces are not dangerous at higher speeds Effects of unbalances are proportional to the square of the speed Effects of unbalances are directly proportional to the speed Unbalanced couples are caused only at higher speeds 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 Reduce maximum opening of port to steam All of these Reduce length of effective stroke of piston Cause withdrawing or throttling of steam Reduce maximum opening of port to steam All of these Reduce length of effective stroke of piston Cause withdrawing or throttling of steam ANSWER DOWNLOAD EXAMIANS APP
