During construction of a highway bridge, the main girders are cantilevered outward from one pier toward the next (see figure). Each girder hasa cantilever length of 48 m and an I-shaped cross section with dimensions shown in the figure. The load on each girder (during construction) is assumed to be 9.5 kN/m, which includes the weight of the girder. Determine the maximum bending stress in a girder due to this load.
The simply supported beam shown in Figure 1 (see next slide) spans a distance of L = 6 m and carries two concentrated loads P, which are applied at a distance of a = 1.5 m from the supports. The beam is fabricated by bolting a steel plate between two wood planks (see Figure 2). The wood planks each have dimensions of b = 30 mm and d = 240 mm. The steel plate has dimensions of t = 9.5 mm and d = 240 mm. The moduli of elasticity of the wood and the steel are 12.5 GPa and 200 GPa, respectively. a) Determine the maximum bending stresses produced in the wood planks and the steel plate if P = 8 kN. b) Assume that the allowable bending stresses of the wood and the steel are 8.25 MPa and 150 MPa, respectively.
