]]>An electric motor weighing 100 kg is supported on isolators having a damping factor of 0.2. It runs at a speed of 1500 rpm and has a rotating unbalance of 10 kgcm. What should be the stiffness of the isolators if the forces transmitted to the foundation is to be less than 10 % of the unbalanced force
