Question:

An electric motor, of mass \(60 \mathrm{~kg}\), rated speed \(3000 \mathrm{rpm}\), and an unbalance \(0.002 \mathrm{~kg}\)-m, is to be mounted on an isolator to achieve a force transmissibility of less than 0.25. Determine (a) the stiffness of the isolator, (b) the dynamic amplitude of the motor, and (c) the force transmitted to the foundation.
