고체역학 (Beer) — Transformations of Stress and Strain: Problem 7.153

7.153 Solve Prob. 7.152, assuming that the gage forms an angle \(\beta = 35^\circ\) with a line parallel to the axis of the shaft. (From Prob. 7.152: A single strain gage is cemented to a solid 4-in.-diameter steel shaft at an angle \(\beta\) with a line parallel to the axis of the shaft. Knowing that \(G = 11.5 \times 10^6\) psi, determine the torque \(T\) indicated by a gage reading of \(300 \times 10^{-6}\) in./in.)
