The steel post shown is cantilevered at its base and supports a weight at its upper end. Considering that buckling can occur about either plane, determine the maximum allowable weight it can support. The post length is L = 4 m, the other cross-sectional dimensions are a = 120 mm and b = 250 mm, and the uniform wall thickness is 15 mm.
