Two 89 X 64-mm angles are bolted together as shown
Two 89 X 64-mm angles are bolted together as shown for use as a column of 2.4-m effective length to carry a centric load of 180 kN. Knowing that the angles available have thicknesses of 6.4 mm, 9.5 mm, and 12.7 mm, use allowable stress design to determine the lightest angles that can be used. Use σY = 250 MPa and E = 200 GPa.
