Re: Pulley Radius: how to factor this into calculations?

Thank you very much for the input!

We are thinking of wrapping 1/8in steel cable around pulleys that are 1/2in in diameter. They need to be as small as possible to fit inside of our elevator assembly.

Our fear is that there is not enough "wrap" around the pulley, and pulling the wire around such a small diameter will be almost akin to pulling the wire across a sharp corner. I am not sure if I described this well enough....
