Frequency of torsional oscillations diminishes

Reference no: EM13660155

A thin steel beam 8.0 m long is suspended from a crane and is undergoing torsional oscillations. Two 80 kg steelworkers leap on to opposite ends of the beam, as shown in Fig. 13.29. If the frequency of torsional oscillations diminishes by 15%, what is the mass of the beam?
