Four 3x3x1/2 equal leg angles are laced together as shown in Figure 4 to form a column section. Determine the Euler (elastic) stress and the critical buckling load for the pin-connected column. E = 200,000 MPa. Proportional limit is 250 MPa. Assume simple span and maximum permissible L/r = 200.
a. L = 11.50 m
b. L = 9.75 m

Properties of one 3 X 3 X 1/2 angle A = 1774 mm? k = 0.92 x 10° mm = 22.81 mm y = 23.67 mm ly = 0.92 x 10° mm ry = 22.81 mm i = 23.67 mm 300 mm L + 300 mm Figure 4
