Question and answer
The Tacoma Narrows Bridge collapsed due to A. resonance. B. frequency modulation. C. beats. D. destructive interference.
The answer is B. frequency. The Tacoma Narrows bridge collapsed due to wind induced resonance on November 7th, 1940. [ Resonance is a process in which an object's, in this case a bridge's, natural vibrating frequency is amplified by an identical frequency. In this case the identical frequency was caused by strong wind gusts blowing across the bridge, creating regions of high and low pressure
above and below the bridge (Bernouli's principle). This produced violent oscillations, or waves, in the bridge leading to its collapse. ]
