Which consequence results when cryogenic fueling weakens a steel column?

💡 Explanation

Reduced buckling load occurs due to **cryogenic embrittlement**, because extreme cold causes a phase change in the metal, reducing its ductility, therefore the lowered elastic modulus precipitates brittle fracture, rather than increased strain hardening seen at higher temperature.
