The beam supports a single live load of 1,540 lb, a uniform live load of 400 lb/ft, a uniform dead load of 180 lb/ft. Determine the maximum positive shear that can be developed at point B. Assume the support at A is a pin and C is a roller. The influence lines for VB and MB are shown, along with the peak values of the influence lines.

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.
