Chapter 6, Problem 6/093 The uniform semicircular bar of radius r = 85 mm and mass m = 2.9 kg rotates freely about a horizontal axis through the pivot O. The bar is initially held in position 1 against the action of the torsional spring and then suddenly released. Determine the spring stiffness kr which will give the bar a counterclockwise angular velocity @ = 4.0 rad/s when it reaches position 2, at which the spring is undeformed. A kT m 1 2 A' (0)
