3.29. A simple structure is found to vibrate as a single degree of freedom system. The spring constant determined using static testing is found to be 2500 N/m. The mass of the structure is 3 kg. By using a simple vibration test, the ratio of successive amplitudes is found to be 1.1. Determine the structural damping coefficient and the equivalent viscous damping coefficient. Determine also the energy loss per cycle for an amplitude of 0.08 m.
