An electric motor, of mass 20 kg and operating speed 1350 rpm, is placed on a fixed-fixed steel beam. The motor has a rotating unbalance of 0.1 kg. m. The amplitude of vibration of the beam under steady-state operation of the motor is suppressed by attaching an undamped vibration absorber under the motor, as shown in the figure below. Determine the mass and stiffness of the absorber such that the amplitude of the absorber mass is less than 4 cm.
