b) The amplitude b of forced vibration in a mechanical system is given by fo b = [(0-o)2 + 4r2o²j2 Show that for i) o<< 00, the response is independent of the mass, ii) for o = Wo, the amplitude at resonance depends inversely on the damping constant r and i11) for o>> 0o, the response is independent of the spring constant of the system.
