A horizontal shaft of 75 mm in diameter and 350 mm in length projects from a bearing as shown in Figure Q4. The vertical load of 10 kN, horizontal compression load of 12 kN and torque, 7 Nm are applied at the free end of the shaft. If the safe stress for the material is 145 MPa and assuming the Poisson's ratio is 0.3. Determine the torque, T to which the shaft may be subjected using the following theories: i) The Tresca Theory, and The Von Mises Theory Bearing 350 mm Figure Q4 10 KN T 12 kN
