What was the name of the bridge that was collapsed by the frequency of the sound waves of a cat's walk?

Question

I saw it in a physics video once but that was freshmen year in high school, I was barely paying attention

Answer 1

Sorry that did not happen. It may have been a scale model built for the purpose, but a cat would not walk at such a perfect pace and would change its steps as the resonance gained amplitude. The Tacoma Narrows bridge in Wash. State collapsed because it resonated in a strong wind, I don't remember the year. Maybe late '50's or early 1960's.

Answer 2

No such bridge. The movie is probably about the Tacoma Narrows Bridge, which was built in Washington in the late 1930s. The bridge had the nasty habit of swaying noticably in the wind as was called "galloping gertie". The bridge came down when the wind velocity was the velocity at which the swaying could not be dampened by the bridge construction, and the bridge fell apart. This phenomenon is actually predicted from an analysis not unlike the quadratic discriminant; when the term becomes =0, this overamplication occurs.

Answer 3

The wind did it.
The Tacoma Narrows Bridge is the longest twin suspension bridge in the world.[1] A pair of mile-long (1600 meter) suspension bridges with main spans of 2800 feet (850 m), they carry Washington State Route 16 across the Tacoma Narrows of Puget Sound between Tacoma and the Kitsap Peninsula, USA. The first bridge, nicknamed Galloping Gertie, was opened to traffic on July 1, 1940, and became famous four months later for a dramatic wind-induced structural collapse that was caught on motion picture film. The first replacement bridge opened in 1950, and a parallel bridge opened in 2007.

Answer 4

I don't know if i have the right bridge but I seen something interesting on discovery channel the other day. A bridge, either this or one simlar was shown to have its suspension beam, cords, shaking violently in a light storm. This happened on one rare occasion and had never happened in a very have storm or sunshower. I was found the in a mild storm with just enough rain to creat a steam of water down the support lines and wind not strong enough to break the steam would elongate the dynamics of the supports line and cause them to shake violently in the wind. When there was a heavy storm the stream of water woudl not form and when there was excess wind the stream would also not form either. By chance the perfect conditions were produced and cause the support lines to shake. I thought it was pretty cool, sorta off the topic but thought I would share
