The beam supports a single live load of 2,350 lb, a uniform live load of 400 lb/ft, a uniform dead load of 160 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.

Choose the equation that will give the largest factored load when D = 36 kip, L = 2 kip, Lr = 12 kip, and S = 20 kip.

Determine the deflection at B that would be caused by the distributed load if the middle support was not there. Let w = 9 lb/in., a = 51 in., and EI = 51 × 106 lb·in.2.

The floor system of a hospital laboratory 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 17.4 in.2 and 32.6 in.2, respectively. Determine the live load acting on beam AB.
