Key Inertia, hmmmm?

Well, the only "mistake" I could find was in the spelling of the word 
"applied" in the excerpt you posted from your physics book. It was 
incorrectly spelled "aplied." No big deal, but hey, you asked...even though 
it wasn't really YOUR mistake! :)

Thanks Calin,

Let's see what mess you get into next time your piano needs work. Looks like 
you will be doing it yourself from now on. Maybe this list will be as 
helpful to you in this pursuit as you have to been to our interests in 
physics.

I have attached a sheet from my notebook on how to begin to use some of the 
principles we have been discussing. This is just the beginning but I thought 
it would be helpful to see how some of the simpler formulas work. Nothing 
like applying this stuff to real objects to learn how to use it.

Calin, please feel free to correct any mistakes I have made.

I should perhaps mention that I am just a piano technician with a few old 
physics books.
