The floor system of an apartment building consists of a 5-inch-thick reinforced concrete slab resting on three steel floor beams, which are in turn supported by two steel girders. The areas of cross section of the floor beams and the girders are 17.7 in.2 and 34.1 in.2, respectively. Determine the dead load acting on beam AB.
