A solid steel bar (G = 11.8 ( 106 psi) of diameter d = 2.0 in. is subjected to torques T = 8.0 k-in. acting in the directions shown in the figure.
(a) Determine the maximum shear, tensile, and compressive stresses in the bar and show these stresses on sketches of properly oriented stress elements.
(b) Determine the corresponding maximum strains (shear, tensile, and compressive) in the bar and show these strains on sketches of the deformed elements.
