A simply supported beam spans 35ft and carries a simply distrusted dead load of 0.2kip/ft including the beam self-weight and live load of 0.8kip/ft. Determine the minimum required plastic section modulus and select the lightest-weight W-shape to carry the moment. Assume full lateral support and A992 steel. Design by (a) LRFD and (b) ASD
