An air compressor of mass 500 kg has an eccentricity of 50 kg-cm and operates at a speed of 300 rpm. The compressor is to be mounted on one of the following mountings:
(a) an isolator consisting of a spring with negligible damping, and
(b) a shock absorber having a damping ratio of 0.1 and negligible stiffness.
Select a suitable mounting and specify the design details by considering the static deflection of the compressor, the transmission ratio, and the amplitude of vibration of the compressor.
