2 t Z nces A torque T = 60 N-m is applied to the shaft EFG, which is running at constant speed and contains gear F. Gear F transmits torque to shaft ABCD through gear C, which drives the chain sprocket at B, transmitting a force Pas shown. Sprocket B, gear C, and gear F have pitch diameters of a = 140 mm, b=233.338 mm, and c = 116.666 mm, respectively. The contact force between the gears is transmitted through the pressure angle = 20. d-30 mm -f-250 mm g-135 mm e=75 mm View a d Combine these stresses and determine the maximum principal normal and shear stresses in the shaft. The maximum principal normal stress is MPa. The maximum shear stress is MPa.
