고체역학 (Beer) — Torsion: Problem 3.154

3.154 In the bevel-gear system shown, \(\alpha = 18.43^\circ\). Knowing that the allowable shearing stress is 8 ksi in each shaft and that the system is in equilibrium, determine the largest torque \(T_A\) that can be applied at A. (From Figure P3.154: Shaft A diameter \(d_A = 0.5 \text{ in.}\), Shaft B diameter \(d_B = 0.625 \text{ in.}\))
