Answer:
Resonance
Step-by-step explanation:
Resonance
It's a natural phenomenon that occurs when a material's natural frequency is matched by any physics event that makes the material to show anomalous greater amplitudes in their oscillations. If the powering phenomena is long and strong enough, it could cause some disastrous outcomes, like of the cited Bridge of the question.
Back on November 7, 1940, 42 mph winds forced resonance and the bridge collapsed. They were considered as normal speed winds but they produced aeroelastic flutter that matched the bridge's natural frequency and destroyed the structure.
