An I section girder or stanchion is constructed from two 80mm x 12mm flanges joined by an 80mm x 12mm web. Four of such girders are mounted vertically , one at each corner of a horizontal platform which the girders support. The platform is 4m above the ground level and weighs 10KN. Assuming each girder support an equal shear of the load, Determine the maximum compressive stress set up in the material of each girder when the platform support an additional load of 15KN. The weight of the girders may not be neglected. The density of the cast iron from which the girders are constructed is 7470kg/m3 please help with the solution
