A customer asked which bell is loudest when wet.

Until today I did not know thin bike bells don't ring well when wet. Try
it - a schpritz of Windex will do.

Yes, resonance is fascinating, and delicate. As Carl explained earlier,
water tends to muffle a bike bell, but would not muffle a (much greater
mass) church steeple bell.

The following link http://www.acoustics.salford.ac.uk/acoustics_info/glass/
has two interesting links within it. One link shows video of the Tacoma
Narrows Bridge. Another link within has slow motion video of a wine glass
shattering.

Is quite fantastic. Who would have believed you could deform glass by
that much without it...ah, as you were.

^^^^^^^^^^^^^^^^^^^^^
Yes, and since the bell cannot be heard, possibly to dumping.

Ah! A three step process: dampened - damped -dumped (the bell, not the
rider,one hopes)

Thanks for giving me an opening to discuss one of my pet peeves.
"Dampening" means adding moisture. "Damping" refers to the absorption of
energy from a vibrating system. Damping is what happens in an auto shock
absorber, or when the soft pedal of a piano is depressed. Dampening is
what happens when someone uses a spray bottle while ironing, or when you
try to ring your bike bell in the rain.

I don't think you have your examples exactly right. I think that when you
try to ring your bike bell in the rain both dampening and damping are
occuring. See Carl's excellent explanation above

Dear Frank,

If a glass rod is free from microscopic defects, you can bend it into
a U-shape:

such stuff.
