A simply supported beam spans 40 ft and carries a uniformly distributed dead load of 2.1 kip/ft plus the beam self-weight and a live load of 3.8 kip/ft. The beam is fully braced such that lateral torsional buckling (LTB) will not occur. Determine the minimum required plastic section modulus and select the lightest W-shape to carry the moment using A992 steel. Specify a camber and check the section compactness. Do not specify camber if deflection is under 0.75 in. WDWL A B Figure 2
