Equal torques T = 5 kip ft are applied to the two steel bars with the cross sections shown. (Note that the cross-sectional areas of the bars are equal.) The length of each bar is 8 ft. Calculate the maximum shear stress and angle of twist for each bar. Use G = 12 x 106 psi for steel. 5 in. (a) 2 in. 10 in. (b) FIG. P3.52 1.0 in.
