The hollow steel shaft (G =83 GPa) must transmit a torque (torsional moment) of 32.5 kN-m. The outside
diameter D of the shaft is 300 mm.
Considering both limitations (in allowable torsional shear stress of 80 MPa and in maximum total angle of
twist of 0.07 degrees per meter), determine the minimum safe thickness of the hollow shaft [in mm).
Note: For the numerical answer, round up to the nearest whole number.
