How does a major news channel get so much easily googleable information wrong? Sullivan was accurate in telling that a guy got stuck on the bridge while it was oscillating and he had to leave his vehicle, but the narrator was wrong when he said he went back to get the dog. The guy who went out onto the bridge was Faquharson, a professor at UW who tried to save the dog after he learned that it was in the car.

Uh, back to the drawing board!

I recently drove over the new bridge that replaced this one

Imagine being the chief engineer of this bridge and you get THAT call

can you imagine time traveling to this event and film it in HD with your future camera next to a old camera user xD

Why not go and film something more important, like The Alamo, The Crucifixion, or The Battle of Hastings? The film of this is poor to cover up that it was a controlled demolition, that's right they pulled the bridge. The footage of it collapsing starts right after the charges fired, you can see all the smoke from them.

@@andrewdeighton5926 controlled demolition?? Try making a wooden bridge (miniature) and give it a wind with your fan. Did it sway? Collapse? Moving? Now imagine it on a large bridge, with bigger wind. It would happen like this. Also, didnt you mind this bridge was built in 1930s and then destructed in 40s like a demolition? its a 10-year old bridge. Have you think? I know its a joke but i wanna to explain.

Shocking that the Tacoma Narrows Bridge passed inspection, was permitted and allowed to open given the dangerous conditions that were known during and after construction. I realize that it was in 1940. However, you don’t need to be an engineer to know that a 6-foot upward/downward sway in only 15 mph winds was an issue and would worsen under more adverse wind conditions.

Yes it depends how the wind had perfect speed to cause oscillations ... Finally due to wind induced vibration the bridge is collapsed

Somanath B - No, the wind speed did not have to be perfect, only strong enough to put energy into the oscillation faster than it could be dissipated.

NOOOO TEH DOGGIE D:

It wasn't the dog owner but another brave man who tried to save the dog. The owner should have taken the dog with him in the first place

I mean, it's not so much the power of the wind as a mistake made in engineering that allows the wind to have such an effect on the oscillation...

Yup. That bridge was both underengineered and inappropriately engineered, given the constant gusty wind conditions in the Narrows. It was originally designed to have triangular trusswork below the roadway with considerable height to stiffen the structure of the roadway, but they changed it to solid box girders only 8 feet high, with solid girders running under the roadway from side to side. Those caught the wind like sails, and caused the frequent up and down motion of the roadway of 6 to 8 feet, which people crossing the bridge noticed all the time and the nickname Galloping Gertie caught on. On the fatal day of the collapse, the wind was gusting up to 46 mph with just the right frequency to get the suspended span of the roadway to start twisting in a rhythmic torsional manner, and the wind gusts were just the right frequency to harmonize with the frequency of the torsional oscillations, so it kept the oscillations going, rather like having someone pushing a child in a swing each time the swing comes back to the pusher. Only an occasional push keeps the swing oscillating front to back. Two reasons for the design change: (1) it used a lot less steel and was quicker to build, so it saved a lot of money and money was tight in 1938 due to the Great Depression, and (2) it was thought the box girder design made the bridge look more elegant because it was more slender and graceful. As a result of this failure, scale models of suspension bridges tested in wind tunnels became the norm -- in fact, they built a scale model of Galloping Gertie as built and got it to do the same thing in a wind tunnel and collapse. So when they replaced the Tacoma Narrows Bridge in 1950, the new bridge was fine, properly engineered and is still in use in 2018. In 2007, a second suspension bridge alongside the 1950 span opened, and each of the two bridges carries traffic in a single direction. In fact, a whole lot of suspension bridges were built around the world after the collapse of Galloping Gertie and not a single one of them has failed. So the engineering mistakes made in the original Tacoma Narrows Bridge made a huge difference as to suspension bridge construction standards.

The thing is the wind wasn't even that fast (35mph?)

it's not a question of how fast the wind was but how that speed had the perfect match with the oscillation rate of the bridge, wich caused its destruction

sometimes cat at the TV and TV shows news reporters that say to you that who is telling the right way and who is telling me that the right way and who is makes sense and who is doesn't make any and who is playing here that which one it is guilty or not guilty sometimes an engineer always do mistakes. because they don't do their homework very good enough One little mistake but once they built it there's no way going back this is once in the past but there to the president Fernando and for the future not to repeat history mistakes again not going to happen if you want to learn about something of an engineer and managers you could choose one of them or do they choose both again whatever you wanted to do because you want to know something about it and it is right front of the news that no one saw this one coming did you want to know something about it and do it because sometimes that is was younger or older if you want to learn something about it something in the past present future if you want to save it in the past kind of upgraded for the future then you could.

Looking at Rose’s associated videos the problem may be that English is not their first language. If so, no offense intended. I sometimes comment that while we’re interested in someone’s comments, without some reasonable use of punctuation and capitalization, understanding becomes too “labor intensive.”
