Resonance Avoidance

Quick fact

The Tacoma Narrows Bridge collapse in 1940 is a classic example of resonance failure: wind-induced oscillations matched the bridge's natural frequency, causing it to twist apart.

Why this is interesting

You've seen a singer shatter a wine glass by hitting just the right note – that's resonance in action. Now imagine designing a skyscraper or a jet engine to survive the same phenomenon; how do engineers prevent such destruction?
