A rod of length 1.5 m is attached to a spring of spring constant, k as shown in Fig. II-1. The rod is released from rest when 0 = 0°. While reaching the position 0 = 90°, the angular velocity of the rod was 2.32 rad/s. If the mass of the rod is m kg, determine the value of the spring constant, k. Assume that the spring is unstretched when 0–0°. Take the mass of the rod (m) as 49kg...

Rod BC has a weight of 50 N. When θ = 0, the spring is
unstretched. If the weight of the rod causes the spring to stretch
as shown, find the angle the spring makes with the horizon, the
force in the spring, and the stiffness of the spring (K).

2. Figure 2 shows the mechanism for a door panel held in place by a bar BC and a torsional spring. The door panel has a mass of 30 kg and held in equilibrium at 0 60. It is required to determine the stiffness (k) of the torsional spring such that the door panel reaches the closed position (0-0") with a zero angular velocity once the supporting rod BC is removed. The mass moment of inertia of the door panel...
