Title: On the Mechanics of the Bow and Arrow
Post by: passion for knowledge on December 04, 2016, 06:34:00 PM

Ran across this while poking around.

Maybe interesting, useful or both.

Hm.  Archery has always been one of my ways to get partial differential equations OUT of my mind!

Hmmm, I glossed over it and didn't see the mechanics I was hoping to find... relative limb balance. I'll look again. Perhaps I missed it.

Nope, not in there.

I'm with GreyGoose on the equations. I can make my way through them, but a lot of my Uni math is a bit rusty these days.

I only posted from the point of view of interest.

Bowjunkie, one of the things about mathematical models is that they always make some assumptions at the start.

They likely assumed perfect limb balance/timing at the get-go.

Yes. I figured he did when he said he assumed both halves of the bow to be identical and so analyzed the top half... or something to that effect.
