Question

A 36-lb motor is bolted to a light horizontal beam that has a static deflection of 0.075 in. due to the weight of the motor. The unbalance of the rotor is equivalent to a weight of 0.64 oz located 6.25 in. from the axis of rotation. The motor rotates at a speed of 1080 rpm. Determine the amplitude of the vibration of the motor assuming that the damping factor c/c_c is equal to 0.055.

The amplitude of the vibration is ________ in.
