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 01 degree per meter), determine the minimum safe thickness of the hollow shaft.
