A 360-lb motor is bolted to a light horizontal beam. The unbalance of its rotor is equivalent
Question:
A 360-lb motor is bolted to a light horizontal beam. The unbalance of its rotor is equivalent to a 0.9-oz weight located 7.5 in. from the axis of rotation, and the static deflection of the beam due to the weight of the motor is 0.6 in. The amplitude of the vibration due to the unbalance can be decreased by adding a plate to the base of the motor. If the amplitude of vibration is to be less than 2.16 × 10??3 in. for motor speeds above 300 rpm, determine the required weight of the plate.
