An internal combustion engine has a rotating unbalance of 1.0 kg-m and operates between 800 rpm and 2000 rpm. When attached directly to the floor, it transmitted a force of 7018 N at 800 rpm and 43,865 N at 2000 rpm. Find the stiffness of the isolator that is necessary to reduce the force transmitted to the floor to 6000 N over the operating-speed range of the engine. Assume that the damping ratio of the isolator is 0.08, and the mass of the engine is 200 kg.
