고체역학 (Beer) — Torsion: Problem 3.51

3.51 The solid cylinders AB and BC are bonded together at B and are attached to fixed supports at A and C. Knowing that the modulus of rigidity is \(3.7 \times 10^6 \text{ psi}\) for aluminum and \(5.6 \times 10^6 \text{ psi}\) for brass, determine the maximum shearing stress (a) in cylinder AB, (b) in cylinder BC.
