During operation a \(100-\mathrm{kg}\) press is subject to the periodic excitations shown. The press is mounted on an elastic foundation of stiffness \(1.6 \times 10^{5} \mathrm{~N} / \mathrm{m}\) and damping ratio 0.2. Determine the steady-state response of the press and approximate its maximum displacement from equilibrium. Each excitation is shown over one period.
