Problem 12.8 Given: In the figure, columns AB and CD have pinned ends, are made of an aluminum alloy (E=72 GPa), and have equal rectangular cross sections of 20 mm by 30 mm. Determine the magnitude of P that will first cause one of the columns to buckle. Assume elastic conditions. Solution: E 72 GPa := I min 30 mm 20 mm () 3 12 21 0 4 × mm 4 = := Sum moments about upper hinge 1500 P 500 P AB 0 = P
