Determine the beam deflection at point H. Assume that EI = 1.30 × 1010 kN-mm2 is constant.

Wind is considered what type of load?

We can use Castigliano’s Second Theorem to calculate the deflections of trusses, beams, and frames.

Determine the beam deflection at point B. Assume E = 236 GPa and I = 221 × 106 mm4 are constant.

The floor system of a gymnasium consists of a 140-mm-thick concrete slab resting on four steel beams (A = 8,600 mm2) that, in turn, are supported by two steel girders (A = 25,200 mm2). Determine the point load acting on girder AD at point C caused by dead load.

Assuming that the live loads are transmitted to the bottom chords of the truss, draw the influence line for the force in member BF. What is the line’s minimum value? Let L = 12 ft.

Determine the vertical reaction force at A. Let M = 60 kN·m, w = 30 kN/m, P = 190 kN, a = 5 m, b = 7 m, and c = 4 m.

The beam is fixed at wall B. Determine the internal bending moment at point C, which is x = 7 ft to the right of support A. Let L = 30 ft, M = 950 lb·ft, P = 775 lb and w0 = 225 lb/ft.

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 CD. Let F1 = 450 lb, F2 = 500 lb, and L = 5 ft.

Determine the magnitude of the largest bending moment in the beam. Assume L = 4 ft, P = 650 lb, and w = 200 lb/ft.
