1.6 (A). An I-seetion girder is constructed from two 80 mm × 12 mm flanges joined by an 80 mm x 12 mm web. Four such girders are mounted vertically one at each corner of a horizontal platform which the girders support. The platform is 4 m above ground level and weighs 10 kN. Assuming that each girder supports an equal share of the load, determine the maximum compressive stress set up in the material of each girder when the platform supports an additional load of 15 kN. The weight of the girders may not be neglected. The density of the cast iron from which the girders are constructed is 7470 kg/m³. [2.46 MN/m².]
