Problem Specification — Lesson 1

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 0.5 m and is 20 m long.  It is constructed of structural steel with a Young’s modulus of 2E+11 Pa and a Poisson’s ratio of 0.3.  Calculate the critical buckling load of the column.
