Short columns or stockier columns fail first by crushing instead of crushing. Because from the above graph, short columns fail first by crushing. The higher slenderness ratio columns are called long columns. Long columns or slender columns fail first by buckling. Because their buckling strength is lower than the yield strength of the column.
