Tacoma Bridge

Thumbs up if you were sent here as part of studying for a Physics class.

30% of the comments about science. 70% about the dog

“The car was abandoned and now one was hurt in the incident” thank god 😅 “However, a small dog” oh god no

I would've enjoyed watching the bridge collapse if you didn't tell me it killed a dog

Did the Engineering professor really need to go all the way out to the middle of the bridge to figure out what was going on? "Hmmmm, I can't quite tell from here, better go to the middle..."

I can't even begin to imagine the phone call the engineer who designed that bridge got that day

to those wondering about the dog: Tubby crouched in the back seat of Leonard Coatsworth's car on November 7, 1940. When the car stopped because of Galloping Gertie's violent motion, Coatsworth abandoned the car. He tried to return to the car for Tubby, but couldn't. The bridge's motion had become too violent. Coatsworth's colleague, photographer Howard Clifford tried, but failed. Professor Farquharson, a dog lover, decided to try. He managed to reach the car, and opened the door to coax Tubby out. He tried to calm the sick, terrified pooch, but Tubby snapped at the friendly hand, nipping the knuckle. Farquharson gave up and staggered back to safety moments before the bridge collapsed. A photo of Farquharson appeared the next day in the Seattle Post-Intelligencer, showing his left index finger wrapped with a bandage. The photo caption read "Token of 'Gratitude.'"

Resonance: this example was shown by my science teacher back in 1982. It never left my mind. I've shown it to my children just now and it still is very impressive!

My physic teaches showed me this video and I couldn't believe what I saw. This is a great example of why physics and science is so awesome!

For all of you who are upset about the dog, the owner tried repeatedly to get the dog out but it was too scared and refused. I saw it on a documentary. Yes, it is sad but the guy had no choice but to run unless he wanted to die.

I drive on this quite often and I think about this every time.

They must've been confused and put rubber instead of concrete...

Why are some people saying it's fake or have something to do with a conspiracy? It's got something to do with the frequency, Learn Science!

I never thought bridges were so flexible and bendy. before we know it, we might have concrete bands instead of rubber bands.

Frequency of the wind became equal to the natural frequency of the suspension bridge which produces a large amplitude due to resonance and suddenly the the bridge stated swaying in to and fro motion which was almost inevitable to get ceased. Eventually the bridge was unable to withstand the resonance due to which this beautiful suspension bridge collapsed 😔....

It's interesting how a particular environment can affect a structure like that. That very same bridge construction (from the same contractor) was used in several other bridges in the US, and they held up just fine. But the winds at Tacoma affected it differently than in other areas, exposing weaknesses that were not apparent in other settings.

To reach our summer cottage we had to cross this bridge.  I am old enough - just - to remember the toll-taker man and the 25-cent toll.  I loved the bridge.  On the day it fell, my mom drove out to the bridge, stopped, having forgotten some food at our home in Tacoma, when she arrived back at the bridge it was gone.

Love the quote at the end of the video: "The new bridge, is completely stable." lollll

How my mood changed when he said there was a dog in the car..

I'm surprised that a steel frame has that much flexibility. Also, I'm amazed that the pavement didn't crack.
