Equal torques are applied to thin-walled tubes of the same
Chapter 3, Problem 3.149(choose chapter or problem)
Equal torques are applied to thin-walled tubes of the same length L, same thickness t, and same radius c. One of the tubes has been slit lengthwise as shown. Determine (a) the ratio \(\tau_{b} / \tau_{a}\) of the maximum shearing stresses in the tubes, (b) the ratio \(\phi_{b} / \phi_{a}\) of the angles of twist of the tubes.
