ResonanceHardQuestion 31177
Question
Tacoma Narrows Bridge (1940) collapsed due to:
- AOverloading by traffic
- BResonance between wind-induced vibrations and natural frequencyCorrect
- CEarthquake
- DCorrosion
Correct answer
Resonance between wind-induced vibrations and natural frequency
Explanation
Wind vortex shedding at the natural frequency of the bridge caused resonant oscillations that grew until the bridge collapsed — a dramatic example of mechanical resonance.
