WebWhen the slenderness ratio exceeds a value of 100 for a strong slim column, failure by buckling can be expected. Columns of stiffer and more brittle materials will buckle at lower slenderness ratios. The constant factor m in Euler's critical-load formula clearly shows that the failure of a column depends on the configuration of the column ends. The basic four … The Euler buckling load can then be calculated as. F = (4) π 2 (69 10 9 Pa) (241 10-8 m 4) / (5 m) 2 = 262594 N = 263 kN. Slenderness Ratio.
