Consider again the system shown in Figure 2.46, reproduced in Figure 5.25. The bar is horizontal when the massless springs are undeformed. Assume that the rod mass is \(m\), and the mass moment of inertia about the torsional spring is \(I_{O}\).

(a) Find the static equilibrium position of the system using the principle of virtual work, and

(b) derive the equation of motion of the system using d'Alembert's principle.
