Why the rhythmic pulse of steam trains can break a bridge
In short: Professor Martyn Pavier investigates how cyclical loading patterns differ from static ones, revealing why material testing is essential for preventing catastrophic failures in load-bearing structures like railway bridges.
This film explores the historical significance of bridge collapses during the age of steam. By examining the physics of how materials respond to repetitive stress, Professor Pavier demonstrates why modern engineering must account for cyclical loading rather than just static weight. This fundamental understanding of material fatigue remains a crucial consideration when selecting materials for modern load-bearing infrastructure.
