Tacoma Narrows Bridge Collapse "Gallopin' Gertie"

Watch the amazing "Gallopin' Gertie" November 7, 1940 film clip.
1940 Tacoma Narrows Bridge
Slender, elegant and graceful, the Tacoma Narrows Bridge stretched like a steel ribbon across Puget Sound in 1940. The third longest suspension span in the world opened on July 1st. Only four months later, the great span's short life ended in disaster. "Galloping Gertie," collapsed in a windstorm on November 7,1940.

The bridge became famous as "the most dramatic failure in bridge engineering history." Now, it's also "one of the world's largest man-made reefs." The sunken remains of Galloping Gertie were placed on the National Register of Historic Places in 1992 to protect her from salvagers.

A dramatic tale of failure and success
The story of the failure of the 1940 Narrows Bridge and the success of the Current Narrows Bridge is a great American saga. When Galloping Gertie splashed into Puget Sound, it created ripple effects across the nation and around the world. The event changed forever how engineers design suspension bridges. Gertie's failure led to the safer suspension spans we use today.

the bridge was just doing yoga excercises

It actually isn't resonance. The cause is a phenomenon called "aeroelastic flutter", completely different from resonance (that would be the marching-sync-bridge-breaking myth). If you look it up, it happened during a windstorm, and the redesing of bridge structures employed methods to avoid fluttering.

And your comments indicated that you are lacking of a sense of humor and reading abilities. Also calculating 1+1 is most likely not part of your skills.

It's obvious that you are one those who live in their own private world. Your comments also indicated that you are nothing more than a troll, whose biggest skill is name calling.

Because its Obamas fault that Mothman destroyed this bridge? Duuuh I think that a no brainer you idiot.

[Cindi Bri]

What does this bridge collapse have to do with Obama?

And so Mothman striked once more. Thanks Obama!

The replacement bridge was known as "Sturdy Gertie".

[Tej Pradhan]

FUCKING HELL HOW THE FUCK DID THAT HAPPEN?

[wu1ming9shi]

waaw, seriously well tell this to my physicist teacher then -_-

[Tristan Bal]

This is real. Even in world war 1 we already have colored video cams. History Channel aired this footage in number of times already.
