A pump system is to be installed as shown in the diagram below. The pump and the basehave a combined mass of 150 kg. The pump operates at 1750 rpm

with a maximum unbalance of 0.002 kg-m. The isolation system has an equivalent stiffness of 7.3 x 106 N/m,and a damping ratio of 0.1. Determine: a) The steady state displacement amplitude of the pump b) The force transmissibility ratio c) The force transmitted to the ground d) Should the physical damping of the isolation be decreased or increased to reduce the force transmitted to the base at the operating speed?
