Transcribed Image Text:The uniform semicircular bar of radius r = 120 mm and mass m = 3.2 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 KT
which will give the bar a counterclockwise angular velocity w = 4.3 rad/s when it reaches position 2, at which the spring is undeformed.
