The uniform semicircular bar of radius r - 150 mm and mass m - 3.5 kg rotates freely about a horizontal axis through the pivoto. The bar is initially held in position 1 against the action of the torsional spring and then suddenly released. Determine the spring stiffness kt 1 which will give the bar a counterclockwise angular velocity w = 3.4 rad/s when it reaches position 2, at which the spring is undeformed. m Answer: Nom/rad
