Hey there, everyone.
I'm an engineer/designer who is working on an interesting little problem. I need to design a drum/reel/spool that can hold a length of filament/rope, L, in as small a space as possible.
So, I'm trying to minimize the interior and exterior diameters of the drum and the filament when completely wrapped together.
I did some calculations yesterday and I think I am taking the correct approach. I am not 100% confident in my math though.
I'm attaching my work in the links below. Hopefully, it's clear enough that this all makes sense. Let me know if it is not.
I'd love some feedback on either the method or the calculations.
Thanks,
Matt
