An electric motor having an unbalance, is mounted on an isolator. Ву varying the speed of the motor, a resonant amplitude of 20 mm was recorded. Beyond the resonant frequency, the Magnification ratio = 1 and the vibration amplitude approached a fixed value of 5 mm. Determine the damping ratio of the isolator.
