bruh

Calatrava te lo clava (el obelisco)

Esta alreves el video xD

This is why soldiers would never march in step over bridges

Funciono dos dias…

Hi I come from Humble PI

This video must've really resonated with the British public

It's all fun and games until the engineers say, "oops".

Who came here after zemtv

Se han lucido, el timo de calatrava....

Torres blancas ❤

El video de metro mas viejo q vi

Aparentemente Aerolineas Argentinas

Y este fue el origen de las 3000 en la L5

More recent study says the problem of bridges and lateral motion from human footsteps is not caused by people walking synchronized as the early studies stated. There have been many cases like this bridge as well. It is heavy in physics, but the top 1/8th of the article is approachable for most people. www.ncbi.nlm.nih.gov/pmc/articles/PMC8664840/

I'm impressed with the author of the video, still active and responds to comments :)

oops

I expected a plot twist

Que bien funciona el obelisco (modo irónico off)

When logic tells you the walking pace of a population's steps would be random enough to avoid large translational forces, the resonant frequency, telling you, you're an idiot.

Who came here after Gujarat Bridge Collapse?

The effects of synchronicity and resonance. This is the reason why soldiers break step when crossing bridges.

I wonder if a cruise ships dampening system, that reacts to cancel out sway, could be used to eliminate bridge sway issues? Water tanks on either side of a section of bridge could work passively or actively. We'd need to treat the bridge as if it had several sections with a dampening system for each one. Perhaps all the tanks could be linked together so the water weight is shared and could be redistributed as needed? The presence of water ballast tanks on a bridge section would already provide some dampening of vibration as it would simply be absorbed by the water inside the tanks. But once sway was introduced the water would resist that sway while an active gyroscopic system could respond faster and more precisely.

Me gustaría conocer la última maquina para dar curvatura a los raíles...( Conformar).....

0:34 boquita

they built it badly on purpose so it could teach thousands of physics students how not to build a bridge.

I’m in DT class watching this

sat in physics rn, resonance

C'est rien c'est la physique

Oh honey look the bridge is shaking!! Hurry get the kids let's go on it. Nothing could ever happen

So called "free thinkers" When they have to cross a bridge

Hi! I was wondering if I could use your video in an explainer on a scientific social platform to illustrate what the principle of resonance is? I will of course give you credits. Thank you!

Its amazing that Japan can replace a road junction where a sinkhole appeared in 7 days and bridges that can withstand earthquakes but in the UK they can't build a bridge that can withstand the walking of people.

So this is how "London Bridge is falling down" was composed

Everyone on that bridge had zero time for simple physics explanations in school. Shows how much people know about how the world is built and works.

What do you want when there are 2k people on a bridge literally making it wobble.

As a engineering student I that see that i am not alone

I came here after reading Humble Pi. Fascinating to watch it happen

Israel

StVO §27 (6) Auf Brücken darf nicht im Gleichschritt marschiert werden. Synchronisation und schon wackelts.

Wow its pretty cool how you can pick out entire groups of people who have synchronized their steps.

Llegué a este video por un comentario en el video de Ter. Super interesante!

Who is here after IELTS passage

Everyone on the bridge walk the same way lol

Lo que no saben es que son los mortifagos

Imagine if those were robots and were able to perfectly match the frequency of the oscillations

y van sin mascarilla!!! están locos!!

there is a reason why military personnel are told to break step the crowd started "Marching" along in unison

Must be the first CZcams video on rocking bridges

*trust science*
