The bar of weight W is pinned at its center O and connected to a torsional spring.
Question:
The bar of weight W is pinned at its center O and connected to a torsional spring. The spring has a stiffness k, so that the torque developed is M = kθ. If the bar is released from rest when it is vertical at θ = 90°, determine its angular velocity at the instant θ = 0°.
