What does EI represent in the expression M/EI?

The floor system of a hospital patient room consists of a 120-mm-thick concrete slab resting on four steel beams (A = 9,200 mm2) that, in turn, are supported by two steel girders (A = 25,607.8 mm2). Determine the live load acting on beam BF.

Determine the vertical displacement of joint B. Assume A = 2 in.2 and E = 29,000 ksi for each member. Let P = 680 lb and L = 8 ft.

Determine the horizontal reaction force at A. Let P1 = 95 kN, P2 = 125 kN, P3 = 80 kN, and a = b = c = d = 3.5 m.

Determine the vertical displacement of joint B. Assume A = 2 in.2 and E = 29,000 ksi for each member. Let P = 760 lb and L = 8 ft.

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.
