Draw shear force and bending moment diagrams for the beam shown. There is an internal hinge at \( \mathrm{C} \). If the beam has a rectangular cross section 6 in. wide \( \times 12 \) in. deep, determine the elastic modulus of the section and the maximum bending stress. (Hint: internal moment at \( \mathrm{C} \) is zero).
