고체역학 (Beer) — Torsion: Problem 3.11

3.11 The torques shown are exerted on pulleys A and B. Knowing that both shafts are solid, determine the maximum shearing stress in (a) shaft AB, (b) shaft BC. From Fig. P3.11, the following values are given: - Torque at A: \( T_A = 300 \text{ N}\cdot\text{m} \) - Torque at B: \( T_B = 400 \text{ N}\cdot\text{m} \) - Diameter of shaft AB: \( d_{AB} = 30 \text{ mm} \) - Diameter of shaft BC: \( d_{BC} = 46 \text{ mm} \)
