A diesel engine of mass 300 kg and operating speed 1800 rpm is found to have a rotating unbalance of 1 kg-m. It is to be installed on the floor of an industrial plant for purposes of emergency power generation. The maximum permissible force that can be transmitted to the floor is 8000 N and the only type of isolator available has a stiffness of 1 MN/m and a damping ratio of 5 percent. Investigate possible solutions to the problem.
