A machine of mass 25 kg is placed on an elastic foundation. A sinusoidal force of magnitude 25 N is applied to the machine. A frequency sweep reveals that the maximum (peak) steady-state amplitude of 1.3 mm occurs when the period of the response reaches 0.22 s. Determine: 1- The damping ratio & 2- The equivalent stiffness of the elastic supporting foundation.
