Shafts A and B are made of the same material and have the same cross-sectional area, but A has a circular cross section and B has a square cross section. Determine the ratio of the maximum shearing stresses occurring in A and B (i.e., TA), respectively, when the two shafts are subjected to the same torque (TA= TB). Assume both deformations to be elastic. Refer to Table 3.1. 92 TA TB The ratio of the maximum shearing stresses occurring in A and B is 1.356
