B What are the physics behind fishing rods?

[physical angler]

Hi everyone,

First post here. Been out of school for a while and quite rusty, but always had an interest in physics, and was pretty good back in the day.

Can anyone help me understand the physics of fishing rods?

How to look at a fishing rod in terms of physics and mechanics? (i.e. is it a spring, is it a beam?) I think I've read something online about long deformation theory. Can anybody provide insight?

I want to run some math to determine how maximum casting distance changes due to different rod lengths, lure weights, length of line hanging from rod tip on the cast, and stiffness of rod. All these variables might be too complex to calculate. If so, please let me know. If I can get just a basic understanding, that would be great. Of course, I would love to be able to calculate my casting distance by plugging in rod-length (casting arc) and lure weight variables, assuming zero air-resistance on the lure and line.

Thank you very much.

Doing a Google search on your thread title turns up quite a few sources of information on this. Have you already read through those?

Hi Berkeman,

Don't I feel dumb? I Googled "mechanics of fishing rods" and came up with a bunch of (what seemed to me) irrelevant articles. Going to have a read-through and I'll be back if I'm still baffled.
