Figure Q3 shows stainless steel shaft consists of solid 40 mm diameter section (1), 30 mm diameter section (2), and the Modulus of rigidity of 70 GPa. At free end of the shaft, the rotation angle needs to be restricted to Ocs 4.5° and the shear stress of the steel is 78 MPa. Calculate: (i) The cross sectional area of sections (1) and (2) (ii) The maximum torque Tc that could be applied at C. To 0.75 m C 1.25 m
