A long, slender structural aluminum[E=69GPa] flanged shape is used as a L=8.0-m-long column. the column is supported in the x direction at base A and pinned at ends A and C against translation in the y and z directions. lateral support is provided to the column so that deflection in the x-z plane is restrained at mid-height B; however, the column is to deflect in the x-y plane at B. assume that bf=90mm, d-126mm, tf=8mm, and tw=5mm. determine the maximum compressive load P the column can support if a factor of safery of 2.4 is required. in your analysis, consider the possibility the buckling could occur about either the strong or the weak of the aluminum column. determine the moment of inertia with respect to the y and the z axes through the centroid of cross section area.
