I've seen this black and white clip several times on t.v and I wanted to know if it was real or not.

That is the Tacoma Narrows bridge; or was, until it fell down and was rebuilt. It is real and it was designed poorly and fell down shortly after being built.

Yes it is. I'm not an engineer but I was told that the current or the motion of the river and wind caused a sympahetic frequency with the steel in the bridge causing it to sway. I think the bridge was in the Northwest but I'm not sure.
I am sure that some engineer will answer this and give you a more precise reason for the sway of the bridge.

I know what you're talking about. In class, I had to watch a video on the design of bridges. I forget the name of it but it was built without taking wind into conciderations - and it subsiquently collapsed a few months after opening. I believe it might have been in Michigan or Wisconsin, but I don't know why I'm thinking that. I believe the clips had cars on it... while it was open it was popular to look out onto the bridge and aucutally watch it sway.
The video was Engineering Disasters, on the History Channel.

If it's the same one I've seen, then yes it's real. My physics teacher showed it to the class-- it has to do with the structure of the bridge - Is it crazy that the bridge is moving or is it crazy that someone would actually drive on the bridge?

Yes, you're referring to "galloping girdie", a bridge that bucked up and down due to resonance from wind whistling through it. Eventually the resonance got so severe that the bridge collapsed (and engineers learned to avoid wind resonance in the future).

Could be. I think it was wind that caused a bridge to do that--had to do with the bridge's natural frequency--the wind happened to make it vibrate on that freq, so it became amplified.
For the same reason, soldiers do not march in step across bridges.

Yes it is real. It was the Tacoma Narrows Bridge, and it collapsed in 1940.

The bridge was in Tacoma, Washington. It's nickname was Galloping Gertie.

Yes. It was the Tacoma Narrows Bridge. You could google for more info.

yes, it's some bridge in Oregon or Washington during a wind storm...actual footage.
