A 50-kg motor is directly supported by a light horizontal beam Problems which has a static deflection of 6 mm due to the weight of the motor. The unbalance of the rotor is equivalent to a mass of 100 g located 75 mm from the axis of rotation. Knowing that the amplitude of the vibration of the motor is 0.8 mm at a speed of 400 rpm, determine

(a) the damping factor c/cc,

(b) the coefficient of damping c.
