고체역학 (Beer) — Torsion: Problem 3.132

3.132 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, respectively, when the two shafts are subjected to the same torque (\(T_A = T_B\)). Assume both deformations to be elastic.
