Steel column with a square cross section.
A solid steel column has a square cross section, is fully fixed at one end, and free at the other end. The column is subjected to a unit load at the free end. Therefore, the resultant buckling multiplier equals the critical buckling load. The result of interest is the lowest (fundamental) buckling mode.
The critical buckling load for Mode 1 equals the buckling multiplier times the applied load of 1.0 N.
