The shaft has an outer diameter of 100 mm and an inner diameter of 80 mm. It is subjected to the three torques T1=4 kN⋅m, T2=19 kN⋅m, T3=15 kN⋅m. The smooth bearings A and B do not resist torque.
Shaft C E has gears at C D and E, with bearing B between C and D and bearing A between D and E. The gears exert the following torques in kilo Newton meters: C, T1 clockwise; D, T2 counterclockwise; E, T3 clockwise.
Determine the absolute maximum shear stress in the shaft.
Express your answer to three significant figures and include appropriate units.
