During operation, the compressor unit of a refrigerator, with mass \(75 \mathrm{~kg}\) and rotational speed \(900 \mathrm{rpm}\), experiences a dynamic force of \(200 \mathrm{~N}\). The compressor unit is supported on four identical springs, each with a stiffness of \(k\) and negligible damping. Find the value of \(k\) if only 15 percent of the dynamic force is to be transmitted to the support or base. Also, find the clearance space to be provided to the compressor unit.
