onsider an electrical motor with mass M = 117 kg located at the tip of a rigid beam pivoted at point A, with the other end supported by a spring and damper with stiffness, k = N/m and damper c = 23 kNs/m, as shown in the figure below. Assume that the rigid beam is massless, the length is L = 1.03 m (horizontal distance between point O and pivot and zero initial conditions. If there is an unbalanced mass of mo = 23.4 kg in the rotating part of the motor, eccentricity is e = 464.88 mm, and the rotor is rotating with a sp w 152 rad/s, determine the total amplitude response of point O in to = 0.005 s. Assume the line of actions of forces created by spring and damper act through point O, the ntre of electric motor.
