[TheForge] Tacoma Narows bridge

[Mike Spencer]

A long time ago (28 Jun 2002), Frosty posted a piece about the Tacoma
Narrows bridge failure.

I see that there is some revised science about how Galloping Gertie
went from undulating mode to twisting mode and ultimately
disintegrated.  "Resonance" is the wrong concept.  The right concept
isn't a great deal different practically but is based on a different
principle of physics.

Not smithing-related but Frosty, at least, had yarns from his Dad
about crossing the bridge before it finally failed.  Metal- and
engineering-related at least.

Happy Solstice, Merry Christmas, Happy New Year and good winter to
y'all.
