An air compressor having a mass of 80 kg and operating at a speed of 600 rpm was recently purchased by ABC corporation. The company is investigating suitable isolators to

mount the compressor to the foundation. It is desired to limit the force transmitted to the base to a Transmissibility Ratio (TR) of 2.5 as the compressor passes through the resonance during startup. In addition, an isolation, of 90% (i.e. 10% TR) is to be achieved at the operating speed of the machine. Design a suitable isolator for the compressor. Your design should specify both the viscous damping coefficient (C) for the damper, and the spring constant (K) for the stiffness element.
