Question: Derive the equivalent viscous damping coefficient for Coulomb damping. Compare the response of a one-degree-offreedom system of natural frequency (35 mathrm{rad} / mathrm{s}) and friction

Derive the equivalent viscous damping coefficient for Coulomb damping. Compare the response of a one-degree-offreedom system of natural frequency \(35 \mathrm{rad} / \mathrm{s}\) and friction coefficient 0.12 using the exact theory to that obtained using the approximate theory with an equivalent viscous damping coefficient.
