Question: consider the problem of an unbalanced machine as shown, with a machine mass of 120 kg, a mounting stiffness and a damping value of 500

consider the problem of an unbalanced machine as shown, with a machine mass of 120 kg, a mounting stiffness and a damping value of 500 kg/s. The unbalanced force is measured to be 374 N at a running speed of 3000 rev/min. Determine the amplitude of the motion due to the unbalanced force. The unbalanced mass is estimated to be 1%
