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..."
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.'"
I think Professor Farquharson also contributed to the research into the aerodynamics of the bridge later on. It's interesting to know that he also witnessed the collapse firsthand.
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!
@Plane lovers alike its not Gravity. It’s resonance with natural vibrations. Natural vibrations are different from forced vibrations which happen at the frequency of an applied force (forced frequency). If the forced frequency is equal to the natural frequency, the vibrations' amplitude increases manyfold. This phenomenon is known as resonance.
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 😔....
its called galloping. the osculating winds.engineers aren't perfect not then not now. some people say W.T.C. towers collapsed because of engineering flaws. i disagree IMO the main cause of twin towers collapse was jumpo jets full of high octane fuel crashing into them.
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.
Nah man, it was a small dog. My dog is no different to a human family member, I would have picked it up regardless. it could bite me, scratch me do whatever it wanted but there'd be a more risk in me squeezing it to death than leaving it behind.
It is a very long bridge. The camera angel makes for tremendous foreshortening, and so the angle of the flex lengthwise along the bridge deck is nowhere near as much as it looks.
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.
natural frequency of oscilation and resonance, when the system doesn't moves towards equilibrium as time passes and instead, amplifies the amplitude of the wave
Leonard Coatsworth, a Tacoma News Tribune editor, was the last person to drive on the bridge: Around me I could hear concrete cracking. I started back to the car to get the dog, but was thrown before I could reach it. The car itself began to slide from side to side on the roadway. I decided the bridge was breaking up and my only hope was to get back to shore." "On hands and knees most of the time, I crawled 500 yards or more to the towers . . . . My breath was coming in gasps; my knees were raw and bleeding, my hands bruised and swollen from gripping the concrete curb . . . . Toward the last, I risked rising to my feet and running a few yards at a time . . . . Safely back at the toll plaza, I saw the bridge in its final collapse and saw my car plunge into the Narrows.[8]
@@bangtansbitchstanlmao2113 sounds like he saw his car plunge off the bridge so not sure any rescuers would've gotten to the car. Plus they were likely trying to help ppl first.
How amazing seeing how physics and nature laws work. Does not matter how big man made structures are, seeing these structures are nothing for these laws when they start working is remarkable.
I'm an engineering and it failed because the steel girders gave way due to fatigue. Fatigue limit is the number of cycles a material can survive while being exposed to a certain stress amplitude (in this case it was very high) and failure occured after a relatively small number of cycles. The cyclic motion occured due to a phenomenon called aeroelastic flutter. Essentially this means aerodynamic forces (wind) coupled with the bridges natural mode of vibration to cause rapid periodic motion.
Yeah, it was. I was like you when I saw the video for the first time. I thought that there was no effort made in saving the dog, but both the owner and the professor tried to save him, but couldn't. As a pet owner, I felt bad for the dog, too. Even if the professor could've gotten the dog out, he would've had to restrain him since he was scared. He had enough difficulty walking back as it was, let alone with a terrified dog in his arms. Still, it was a shame.
I remember watching this video back in 2009, when I discovered TH-cam. I genuinely thought it had happened at the time, and didn’t know it was a historical archive. I also couldn’t believe it my eyes.
I've been across this bridge many times (the new one that replaced the failed one. It's still on the bottom of the Tacoma Narrows). The new, redesigned bridge deck design was tested in a wind tunnel at the University of Washington before it was built. Theodore von Karman participated in the official inquiry. The deck was not replaced until 1950 due to WW2.
I was born and raised right by that bridge. As a matter of fact, not only was my grandpa on the team that rebuilt the bridge after it collapsed, but he was one of the last people off before it fell.
I went to school with the son of the man that took most of the movies of the collapse. He made millions from that. I was born in 1944 and remember taking the ferry from Gig Harbor to Tacoma after it fell. The fare on the next bridge was $1.00 per car/driver and a dime per passenger over ten years old. That bridge built in 1950/1951 does sway tho. We had a big wind storm in 1964? and we were on the Gig Harbor side at the span drive in (hamburger place) and you could lean up against the building so your head wouldn't and you could watch the the bridge disappear and five minutes later you could see the whole thing. I was surprised they didn't shut it down but they have a few times since then for that. There was four lanes on that bridge with 18in grating between the lanes for wind relief which led to some interesting lane changing when it was windy, especially if you were in a small car because the wind would come up through the grating. I have seen smaller cars lifted enough that they moved over half a lane. Needless to say that shortly there were big signs that said do NOT change lanes.
BTS World the dog didn’t know any better, yes if you are wondering “he didn’t want his life to be saved!?” Then yes....you could say that....if you can’t see how a dog didn’t know any better then I can’t help you
I had dream about this bridge many times 10 or 15 years ago, I was on the bridge and try to balance my body not to fall, I was terrified in my dream and felt so lucky it was just a dream. Can’t believe it ACTUALLY HAPPENED in 1940.
That's okay. When I first heard of this story on the Weather Channel, I felt the same way. I was enraged that they would leave the dog behind, but then I learned that both the owner and the professor tried their best to get him out and he wouldn't cooperate. I imagine that he might have gotten underneath the seat where they couldn't reach him, but was far out enough for him to bite them. I'm sure that they both felt bad that they couldn't save the dog. I was sad for the dog, too.
The first time I saw this footage was on an episode of “Ripley’s Believe It Or Not” narrated by Jack Palance. The next time I saw it was the very first thing my Physics teacher showed in my very first class in high school (1985)!
I remember watching this in 5th grade because the topic was Bridges and our teachers talked about the oscillation, obviously not using the word but instead saying waves, when strong enough, can cause movement in bridges, especially if built at a bad angle and direction perpendicular to normal winds…
@SidneySage93 Yeah, the wind transferred more energy to the bridge during each vibration than it could lose during the same vibration. This caused torsional vibrations (where one side went up, the other down, and the middle remained at rest), eventually building up enough energy to cause extremely large amplitudes of vibration, causing the bridge to collapse under the strain. Hope that cleared it up :)
Had to watch this on 8mm film in school as a kid. They called the Narrows Bridge "Galloping Gerdy". Too bad about the dog. The Narrows Bridge is a MUST STUDY for bridge architects all over the world. 👍
