An A-36 steel beam of following cross section is part of a bridge and it is subjected loading as shown. 35 ft 250 lb/ft 10 in 35 ft 25 in 50 ft 25 in 600 lb/ft 2 in 50 ft Assume that the bridge has a self-weight of 250 lb/ft and due to the truck, the loading is now 600 lb/ft for the 50 feet section as shown in the picture above. Now if the maximum bending moment due to the truck is 865.625 kip-ft, that translates to a maximum bending stress as shown in the table below. Maximum Bending Cross-sectional shape Yield strength of steel Moment of ine of beam A-36 stress (kpsi) 9.97 kpsi Rectangular 36 kpsi 21.633 kpsi I-shaped Beam 36 kpsi The cross-sectional dimensions of both shapes are shown below. 35 ft 10 in 250 lb/ft in 35 ft (in²) 13020 6290 Consider yourself as an engineer assigned to this bridge construction and discuss the
