Question: Part A Determine the angles ( theta ) for equilibrium of the 8 - lb disk using the principle of the virtual

Part A
Determine the angles \(\theta \) for equilibrium of the 8-lb disk using the principle of the virtual work. Neglect the weight of the rod. The spring is unstretched when \(\theta=0^{\circ}\) and always remains in the vertical position due to the roller guide.
