A composite shaft consists of a brass sleeve securely bonded to half steel shaft, fixed atend A as shown in Figure 1. The brass sleeve and steel shaft have a modulus rigidity Gb= 40 GPa and Gs = x0 GPa. The length of the assembly is L = 400 mm. The outerdiameters of the shaft and sleeve are d1 = 70 mm and d2 = 90 mm, respectively. Giventhe shear stress of brass is τb = 70 MPa and shear stress of steel is τs = 110 MPa.[Note: x value - Use the last non-zero digit from your group number. If the group numberis zero, use the second last digit instead. For example, if your group number is 5, your xvalue is 5 and Gs = 50 GPa; if your group number is 10, your x value is 1 and Gs = 10GPa.] In this situation, Group number is 2. 1) Write the equations of equilibrium for AB and BC section of the shaft in terms of Twith the help of free body diagrams. 2) Determine the polar moment of inertia for brass sleeve and steel shaft.
