Gere & Goodno — Torsion: Problem 3.5-1

3.5-1 A circular copper bar with diameter \(d = 75 \text{ mm}\) is subjected to torques \(T = 3.4 \text{ kN}\cdot\text{m}\) at its ends. Find the maximum shear, tensile, and compressive stresses in the bar and their corresponding strains. Assume that \(G = 41 \text{ GPa}\).
