Question

A single rotor of mass 7 kg is mounted midway between bearings on a steel shaft of 1 cm diameter. The bearing span is 0.4 m. It is known that the c.g. of the rotor is 0.025 mm from the geometric axis. If the system rotates at 1000 rpm, find out the amplitude of vibration, the dynamic load transmitted to the bearings and the maximum stress in the shaft,​
