Theory of Machine The static balancing is satisfactory for low speed rotors but with increasing speeds, dynamic balancing becomes necessary. This is because, the Effects of unbalances are directly proportional to the speed Unbalanced forces are not dangerous at higher speeds Unbalanced couples are caused only at higher speeds Effects of unbalances are proportional to the square of the speed Effects of unbalances are directly proportional to the speed Unbalanced forces are not dangerous at higher speeds Unbalanced couples are caused only at higher speeds Effects of unbalances are proportional to the square of the speed 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.
