The floor system of a hospital patient room consists of a 3-inch-thick reinforced concrete slab resting on four steel beams (A = 19.8 in.2), which are supported by two steel girders (A = 33.4 in.2). The girders, in turn, are supported by four columns. Determine the live load acting on column H.

The floor of an apartment building is subjected to a uniformly distributed load of 48.5 psf over its surface area. Determine the axial load acting on column H.

The truss is pin supported at A and rocker supported at E. Assume all members are pin connected. Determine the magnitude of the force in member AB. Let F1 = 450 lb, F2 = 800 lb, and L = 5 ft.

Determine the vertical reaction force at A. Let w = 26.4 kN/m, a = 5 m, and b = 10 m.

Determine the magnitude of the largest shear force in the beam. Assume L = 1 ft, P = 750 lb, and w = 200 lb/ft.

Determine the horizontal reaction force at A. Let P1 = 150 kN, P2 = 115 kN, P3 = 110 kN, and a = b = c = d = 3.6 m.

The beam is fixed at wall B. Determine the internal shear force at point C, which is x = 4 ft to the right of support A. Let L = 30 ft, M = 1,050 lb·ft, P = 850 lb and w0 = 200 lb/ft.

The beam is fixed at wall B. Determine the internal shear force at point C, which is x = 5 ft to the right of support A. Let L = 30 ft, M = 950 lb·ft, P = 825 lb and w0 = 200 lb/ft.

Which members are zero-force members? It is simply supported with a roller at A and a pin at E.

The truss is pin supported at A and rocker supported at E. Assume all members are pin connected. Determine the magnitude of the force in member DE. Let F1 = 300 lb, F2 = 650 lb, and L = 5 ft.
