PHUB. 0.3-3 8.5-4 A segment of a generator shaft is subjected to a torque T and an axial force P, as shown in the figure. The shaft is hollow (outer diameter d₂ = 280 mm and inner diameter d₁ = 230 mm) and delivers 1800 kW at 4.0 Hz. If the compressive force P = 525 kN, what are the maximum tensile, compressive, and shear stresses in the shaft? T
