Which outcome results when early steam engine boilers exceed their material's tensile strength limits?

💡 Explanation

When boiler pressure exceeds tensile strength, hoop stress causes rapid crack propagation because the metal can no longer withstand the forces, leading to sudden volume expansion and steam release. Therefore a catastrophic explosion results, rather than oxidation, inefficiency, or increased consumption which arise from different operational problems.
