1. Figure 1 shows a rigid bar of length l, hinged at one end, free at the other, and supported through a frictionless ring that is connected to a spring and dashpot system. The spring has are undeformed. In addition, the spring and dashpot can only move horizontally. The free end of the rod is loaded with a force P whose direction remains vertical during the motion. Also, the moment of inertia of the rigid bar about the pivot point is I, and the gravity can be ignored in this problem. Consider only small angular position Derive the equation of motion of the rigid rod. [Hint: sin θ ~ θ and cos θ ~ 1.1
