Question: 4 a 225kg motor is supported by an elastic pad...

Question details

4 A 225-kg motor is supported by an elastic pad that deflects 6 mm when the motor is placed on it. When the motor operates at 1750 rpm, it oscillates with an amplitude of 2.5 mm. Suppose a 680-kg platform is placed between the motor and the pad. Compute the oscillation amplitude that would result at 1750 rpm.

Answer: X = 5.99e-4m (using g = 10 m/s^2)

Not sure how this is the answer.
