The electric motor of total mass of 30 kg is supported by four identical Springs of stiffness k = 8 kN/m each. The mass center of the 8-kg armature is 250 mm from the axis O of the armature.

(a) Determine the resonant speed of the motor.

(b) Find the amplitude of the steady-state vibration if the motor is running at twice the resonant speed.
