A diesel engine of mass \(300 \mathrm{~kg}\) and operating speed \(1800 \mathrm{rpm}\) is found to have a rotating unbalance of \(1 \mathrm{~kg}-\mathrm{m}\). 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 \(8000 \mathrm{~N}\) and the only type of isolator available has a stiffness of \(1 \mathrm{MN} / \mathrm{m}\) and a damping ratio of 5 percent. Investigate possible solutions to the problem.
