Since this is the case and the formulas in Table 11-1 hold only in the elastic range, the empirical formulas for allowable loads given in Section 11.7 are most useful for practical design. However, the formulas in Table 11-1 are useful as a guide to design, especially when empirical formulas are not available for a given case.

 · 4.0 Axis of Buckling. We recall from the equation for the buckling load that it is a function of I, the second moment of area of the cross-section: So for a given cross-section, a column will always buckle about the axis with the lower second moment of area, the 'weaker' axis. This assumes that both axes have equal restraint.
