Raw Video: Russian Bridge Sways in the Wind

A bridge in Volgograd in southern Russia has been closed after it started to sway dangerously. Several people were travelling across the bridge in cars when it started moving, but there were no injuries reported. (May 22)

It is an example of natural harmonics. Do a search for "Tacoma Narrows", a video lesson every physics major should take.

In Soviet Russia the wind doesn't blow it sucks..

Banana Bridge !

@classysassy3

It was covered by several news agencies. Its real.

[classysassy3]

This is fake. Look closely everyone.

@MrAshLC the waves are different because it's structure is freely moveable. this is a hard structure. steel can bend however traditional concrete can't it will only take so much pressure before it cracks and in this video the concrete appears to shrink and expand in certain parts any concrete that cracked would of eventually collapsed this bridge or show signs of collapsing

The dramatically visible, rhythmic twisting that resulted in the 1940 collapse of "Galloping Gertie," the original Tacoma Narrows Bridge, has sometimes been characterized in physics textbooks as a classical example of resonance. However, this description is misleading. The catastrophic vibrations that destroyed the bridge were not due to simple mechanical resonance, but to a more complicated interaction between the bridge and the winds passing through it - phenomenon known as aeroelastic flutter

@kwldude search up a standing wave. This bridge is doing the same thing. Both are form of resonant harmonic motion.

And concrete and steel can bend, if they didnt the bridge would break. Same as how an Aircraft wing needs to flex.. otherwise it would just snap off.

@kint909 tacoma narrows bridge is only fixed to the ground at certain points. the majority of the bridge is held up by strong steel wires there isn't much to stop it swaying, where as this bridge is fixed to the ground all the way across if you pause at 0:35 you can see how the size of the concrete is big on one point and small on another if anyone can explain how concrete and metal can bend without losing shape or breaking i will accept this as a possibility.

@kint909 I'm still thinking it's not possible

tacoma narrows was a suspension bridge and it could happens

in case of russian bridge which is normal type with many support below it's sick fake - look on the concrete on the side - look how its look with tacoma and then look on the russian

sorry but takoma looks autentic and in case of russian it's impossible - every bridge engineer will tell you

be more realistic people - do not believe in everything

@kwldude Well, look up Tacoma Narrows for something closer to you...
