- The Uniform Semicircular Bar Of Radius R 165 Mm And Mass M 3 0 Kg Rotates Freely About A Horizontal Axis Through The 1 (60.71 KiB) Viewed 25 times
The uniform semicircular bar of radius r = 165 mm and mass m = 3.0 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 = 3.1 rad/s when it reaches position 2, at which the spring is undeformed. 2 (10) RT m Answer: K+ = i - A' N•m/rad
