The cylindrical shaft has simultaneous loads of P = 88 KN, M = 12 kN-m, and T = 25 kN-m. The stress concentrations were found to be Scc = 3.6 (axial), Scc = 3.2 (bending), and Sc = 2.1 (torsion). Given b = 83 mm, what is the maximum based on the given coordinate system. Calculate your answer in MPa
