1 (40 Points) a. Construct the shear and bending moment diagrams for the beam shown. List all of the pertinent values including the location and magnitude of maximum shear and bending moment. Indicate each value in the diagrams (just like we did for all solved problems) and indicate whether each line segment in the bending moment diagram is linear or parabolic, using L or P. Make sure to include a complete FBD.  b. The beam is a W 12 x 72, what is the maximum bending stress, fb (or sometimes written σb), developed at 4.5 ft from A?
