The mass m , stiffness k and the natural frequency Wn of an undamped Single degree of freedom system are unknown. These properties are to be determined by harmonic excitation tests. At an excitation frequency of 4 Hz, the response tends to increase without bound(ie a resonant condition). Next, a weight of deltaW= 5lb is attached to the mass m and the resonance test is repeated. This time resonance occurs at a frequency of 3 Hz. Determine the mass and the stiffness of the system.
