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 2.22 mm 2.50 mm 2 mm 3.0 mm 2.22 mm 2.50 mm 2 mm 3.0 mm ANSWER DOWNLOAD EXAMIANS APP
