A vertical column fixed at one end is subjected to a compressive axial load at the free end. The column’s section modulus, EI, is 9.82 × 105 Nm2 and the cross-section area is 7.85 × 10−3 m2. The length of the column is 2 m. The yield stress of the material is 145 MPa. If the column can fail either in buckling or by Tresca’s criterion, the maximum load that the structure can safely sustain is _____ kN (rounded off to one decimal place).
Answer: 603.5 to 607.5
