Determine the vertical reaction force at A. Let M = 140 kN·m, w = 35 kN/m, P = 100 kN, a = 4 m, b = 7 m, and c = 5 m.

To determine the maximum positive shear value due to a single moving concentrated load, the load must be placed at the location of the maximum positive ordinate of the influence line.

Which boundary condition is true for this cantilever beam, where the origin is at H?

Determine the beam deflection at point H. Assume that EI = 4.96 × 1010 kN-mm2 is constant.

The floor system of a school classroom consists of a 3-inch-thick reinforced concrete slab resting on four steel beams (A = 16.1 in.2), which are supported by two steel girders (A = 32.6 in.2). The girders, in turn, are supported by four columns. Determine the live load acting on column B.

Determine the beam deflection at point B. Assume E = 220 GPa and I = 234 × 106 mm4 are constant.

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.
