Question

Tacoma Narrows Bridge (1940) collapsed due to:
  1. A
    Overloading by traffic
  2. B
    Resonance between wind-induced vibrations and natural frequency
    Correct
  3. C
    Earthquake
  4. D
    Corrosion

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.
