Problem E2] A solid steel shaft ABCDE (Fig. 3-17) having diameter d = 30 mm turns freely in bearings at points A and E. The shaft is driven by a gear at C, which applies a torque T2 = 450 N-m in the direction shown in the figure. Gears at B and D are driven by the shaft and have resisting torques T₁ = 275 N-m and T₂ = 175 N-m, respectively, acting in the opposite direction to the torque T₂- Segments BC and CD have lengths LBc=500 mm and L = 400 mm, respec- tively, and the shear modulus G = 80 GPa. Determine the maximum shear stress in each part of the shaft and the angle of twist between gears B and D. T₁ T2 T3 LBC-LCD
