A hoisting drum, having a weight \(W_{1}\), is mounted at the end of a steel cantilever beam of thickness \(t\), width \(a\), and length \(b\), as shown in Fig. 5.34. The wire rope is made of steel and has a diameter of \(d\) and a suspended length of \(l\). If the load hanging at the end of the rope is \(W_{2}\), derive expressions for the natural frequencies of the system.
