Given a steel column (E = 30 × 106 psi, _
= 0.3), of length 10 in., with a square cross section 1 × 1 in.

(A = 1, I = 1/12). One end is fixed and the other is free
(Figure 13.14).

(a) Determine the buckling load by ANSYS using 10 Beam3
elements (Section 15.23).

(b) Compare that result with the theoretical buckling
load.
