Question

4. (20 points) Referring to the beam shown in Figure 1, do the following: a) Find the reactions at the supports. b) Draw the shear force and bending moment diagrams, indicating the locations and values of the maximum shear and and the maximum bending moment. c) Assuming that the cross section of the beam is the section shown in Figure 2, find the maximum compressive and tensile bending stresses in the section and indicate where they occur. d) Assuming now that the cross section of the beam is the section shown in Figure 3, find the maximum shear stress and indicate the point(s) in the section where it occurs. Please show all your work.
