The A-36 hollow steel shaft is 2 m long and has an outer diameter of 40 mm. When it is rotating at 83 rad/s , it transmits 32 kW of power from the engine E to the generator G. The shear modulus of elasticity for A-36 steel is 75 GPaILIILI
Determine the smallest thickness of the shaft if the allowable shear stress is ?allow = 140 MPa and the shaft is restricted not to twist more than 0.05 rad. t=?
