- The Uniform Semicircular Bar Of Radius R 160 Mm And Mass M 3 4 Kg Rotates Freely About A Horizontal Axis Through The 1 (117.72 KiB) Viewed 23 times
The uniform semicircular bar of radius r = 160 mm and mass m = 3.4 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 = 3.8 rad/s when it reaches position 2, at which the spring is undeformed. RT 1 A m Answer: Kr= i Nom/rad
