The shaft shown in Figure 4 is loaded with concentrated torques at B, C, and D, and is fixed at A. (i) Draw a torque diagram for the shaft and give the value of the internal torque in each section of the shaft. (You may use the method of sections, or the graphical method). (ii) The shaft is constructed from two separate pieces that are joined together between B and C using 12 bolts that are uniformly pitched and 8 mm in diameter. The radius of the mating surface between the pieces of shaft is 120 mm. Determine the shear stress in each bolt. (Draw an appropriate FBD and show the equilibrium calculations). Hint: Consider a FBD of the right piece of the shaft with the bolts removed, and apply the torque equilibrium condition.
