An aluminum column built into the ground has length, L = 2.2 m, and is under axial compressive load P. The dimensions of the cross-section are: b=210 mm and d = 280 mm a. Obtain the necessary material properties from the applicable table in the text book. Calculate the critical load, PCR, to buckle the column. HINT: use the smaller value between Ix and ly b. c. If the allowable compressive stress in the Aluminum is 240 MPa, is the column more likely to buckle or yield? d. If the factor of safety, na, is 1.95, what is the allowable buckling load?
