An unbalanced small motor with me-1.2 kg.m is directly bolted to a machine with a mass of 500 kg. The machine is attached to the floor using an isolator with k=75000 N/m, e=1850 Ns/m (Weight of the motor is neglected.) a) Determine that how much percent of the force is transmitted to the floor if motor turns with n-250 rpm. b) Determine the rotation speed of the motor corresponding to the damped natural frequency of the system. e) Determine the vibration displacement amplitude at the speed calculated in part b).
