The shaft AC has a hollow section from A to B and a solid section from B to C. The shaft has an outer diameter of 100 mm, and the thickness of the wall of the hollow segment is 20 mm. Determine the maximum shear stress in the solid shaft.  

Consider the beam shown in the figure below. Determine the vertical reactions at A and C. Draw the shear and moment diagrams for the entire beam, specifying values at changes in loading. Write the equations for shear and moment for the section of the member between A and B. Determine the maximum bending moment [Let x be the distance measured from left end of the beam]  Submit your handwritten solution in the submission section and choose from the menu the answer closest to your solution.
