During construction of a highway bridge, the main girders as shown in Figure Q5(a) are cantilevered outward from one pier toward the next. Each girder has a cantilever length of 48 m and an I-shaped cross section with dimensions shown in the Figure Q5(a). The load on each girder (during construction) is assumed to be 9.5 kN/m, which includes the weight of the girder. Notice that there are four girders used in the construction of the bridge. Determine the maximum bending stress in a girder due to this load.
