The shaft is made from a solid steel section at AB and a tubular portion made of steel and having a brass core. If it is fixed to a rigid support at A, and a torque of 50 lb.ft is applied at the end at point C. Determine the following if the torque applied at point Cis 100 lb-ft: VW 0.5 in I in 1.The angle of twist that occurs at point C. 2.Compute the maximum shear stress in brass. 3.Compute the maximum shear stress in steel. (Shear modulus of steel is 11.5 x 106 psi and for brass 5.6 x 10 psi).
SS 304 steel shaft is 3 m long and has an outer diameter of 60 mm. When it is rotating at 60 rad/s, it transmits 30 kW of power from the engine to the generator. Determine the following: smallest thickness of the shaft if the allowable shear stress is 150 MPa and the shaft is restricted not to twist more than 0.08 rad. Use G for steel = 83 GPa. The percentage savings in weight had the generator utilized a solid shaft. Assume same material, length and torque capacity.
