An equal-leg angle section of length L = 12 ft is to be used to support a compressive load of P = 20 kips with a factor of safety of 2.5 against elastic buckling.17 Assume that the ends of the column are pinned in a manner that permits it to buckle in any direction. From Table D.5 of Appendix D, select the lightest steel section that meets the design requirements. Let E_st = 29(10³) ksi and σ_Y = 36 ksi.
