Assuming that the live loads are transmitted to the bottom chords of the truss, draw the influence line for the force in member BF. The line’s maximum value occurs _______. Let L = 20 ft.

Assume that w0 = 180 N/m and L = 2 m. Determine the shear-force equation V(x) for this beam and loading.

Determine the magnitude of the largest shear force in the beam. Assume L = 5 ft, P = 600 lb, and w = 150 lb/ft.

The floor system of a gymnasium consists of a 140-mm-thick concrete slab resting on four steel beams (A = 8,700 mm2) that, in turn, are supported by two steel girders (A = 25,300 mm2). Determine the point load acting on girder AD at point C caused by dead load.

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.
