A 30-kg compressor is mounted on an isolator pad of stiffness \(6 \times 10^{5} \mathrm{~N} / \mathrm{m}\). When subject to a harmonic excitation of magnitude \(350 \mathrm{~N}\) and frequency \(100 \mathrm{rad} / \mathrm{s}\), the phase difference between the excitation and steady-state response is \(24.3^{\circ}\). What is the damping ratio of the isolator and its maximum deflection due to this excitation?
