Derive the equation of motion and find the steady-state response of the system shown in Fig. 3.44 for rotational motion about the hinge \(O\) for the following data: \(k_{1}=k_{2}=5000 \mathrm{~N} / \mathrm{m}\), \(a=0.25 \mathrm{~m}, b=0.5 \mathrm{~m}, l=1 \mathrm{~m}, M=50 \mathrm{~kg}, m=10 \mathrm{~kg}, F_{0}=500 \mathrm{~N}, \omega=1000 \mathrm{rpm}\).
