Normally you'd expect the Q factor of a standing tape drive to be small enough that you'd be unable to come anywhere close to knocking it over with the tiny kicks from the reels.


Wouldn't you have said the same thing of the Tacoma Narrows Bridge?


I probably would, yeah, unless I actually took the time to examine the design and calculate Q. I'd've been wrong in that case.

Actually, I probably wouldn't, because if it had occurred to anyone that they ought to ensure that the bridge design had no high-Q vibrational modes, the problem would have been found and averted before the first caisson was sunk.


I have the sudden urge to build a weighted cabinet and see if I can knock it over with fast-forwards/rewinds. I've got a couple engineer friends who could run the numbers, but nothing would quite compare to the satisfaction I would feel if I could actually do it.


Can't we get Mythbusters to do it?


I think that's actually a great idea. Anyone know how to throw suggestions their way?
