Linear Column Buckling

Created using ANSYS 13.0

Problem Specification

Consider the column in the figure below.  It is pinned on both ends and supports an axial load.  The column has a circular cross section with a diameter of .5m and is 20m long.  It is constructed of structural steel with a Young’s modulous of 2E+11 Pa and a poisson’s ratio of .3.  Calculate the critical buckling load of the column.
