A mild steel circular column 1.2 m long with a diameter of 8 mm is axially loaded based on Euler's Buckling theory. The column is fixed at one end and free at the other, having a maximum deflection of 40 mm. If the elastic modulus E = 2 × 105 N/mm2, find the maximum compressive stress sustained by the column at crippling load.
- 1269.72 N/mm2
- 267.43 N/mm2✓
- 31.37 N/mm2
- 4134.86 N/mm2
Correct answer
67.43 N/mm2
