And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

Bridge in China sways so much in the wind it has to be closed.
A perfect example of harmonic resonance. Dr. David Goodstein explained this in his PBS show The Mechanical Universe and Beyond. You can find it on Youtube.
I guess one of the intellectual properties those chinese pricks didn't steal and learn from was the galloping girdie Tacoma Narrows bridge film that every schoolkid in this country is shown...now if they also build that bridge with their shit hardware, I'm pretty sure their bridge will end up the same way galloping girdie did...in the river below...it couldn't happen to a nicer bunch!
China's Galloping Gertie?
ReplyDeleteExactly what I was thinking - a modern case of natural frequency aligning with seasonal winds. I guess nobody checked that one out before building it.
ReplyDeleteI've seen film of the original Tacoma Narrows Bridge really going to town before it collapsed into the Puget Sound.
ReplyDeleteThe Communist version of the Tacoma Narrows. Maybe their engineers aren’t that smart after all.
ReplyDeleteSome people have to piss on the electric fence.....

ReplyDeleteChina generally does excellent civil engineering. How they screwed up the aerodynamics is a mystery. Even Roebling stiffened his suspension bridges.
