Theory of Machine A shaft has an attached disc at the centre of its length. The disc has its centre of gravity located at a distance of 2 mm from the axis of the shaft. When the shaft is allowed to vibrate in its natural bow-shaped mode, it has a frequency of vibration of 10 rad/s. When the shaft is rotated at 300 r.p.m., it will whirl with a radius of 3.0 mm 2.22 mm 2 mm 2.50 mm 3.0 mm 2.22 mm 2 mm 2.50 mm 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 couples are caused only at higher speeds Unbalanced forces are not dangerous at higher speeds Effects of unbalances are directly proportional to the speed Effects of unbalances are proportional to the square of the speed Unbalanced couples are caused only at higher speeds Unbalanced forces are not dangerous at higher speeds Effects of unbalances are directly proportional to the speed Effects of unbalances are proportional to the square of the speed ANSWER DOWNLOAD EXAMIANS APP
