cavanami Posted August 9, 2007 Report Share Posted August 9, 2007 I have seen vibration crack motor mounts, engine exhaust stacks, machinery foundations...I would take the "myth busters" with a large grain of salt. Civil engineers go to great lengths to isolate any equipment that is causing vibrations in buildings. My cousin has made big $$$ doing vibration analysis consultations and studies. All the ships I have worked on had a certain speed range barred (not allowed) because of vibration characteristics of the propellers/shaft/engines/hull design, etc. Link to comment Share on other sites More sharing options...
The_Munchmaster Posted August 9, 2007 Report Share Posted August 9, 2007 I can't underatand why eveyone is still talking about this bridge collapse. A few folk died. Big deal. There are waay bigger loses of live elsewhere in the world that deserve bigger attention. Link to comment Share on other sites More sharing options...
Guest lazyphil Posted August 9, 2007 Report Share Posted August 9, 2007 i think it deserves reporting, it was a terrible tragerdy and looked very dramatic. a few folk died yes, and a big deal to those who lost them. Link to comment Share on other sites More sharing options...
The_Munchmaster Posted August 9, 2007 Report Share Posted August 9, 2007 I agree that it deserved reporting and sorry for all those who lost someone, but it's minor news compared to the other losses of life in the world. Link to comment Share on other sites More sharing options...
shygye Posted August 9, 2007 Report Share Posted August 9, 2007 Then you should just ignore this thread.

The bridge did not collapse from resonance since there was no build up swaying or wave amplitude. Link to comment Share on other sites More sharing options...
Guest lazyphil Posted August 9, 2007 Report Share Posted August 9, 2007 dafur, for example, needs to make more headlines no doubt at all on that, but this still warrants the coverage. i know its strange. a ski lift disaster in austria can make bigger headlines than a earthquake in remote china wiping out 10k people on the same day.
