# Stresses in the bending of a thin walled cylinder

mechE235
I am looking into the bending of a thin walled cylinder about it's neutral axis. Should be simple enough, it is just Mr/I. However, that is the maximum stress at the outer fibers of the cylinder and I want to find an approximate expression for the load per unit circumference on a small element at the outer fibers of the cylinder. Anyone have a solution for this? A member of a team where I used to work had a solution, but I forgot it.
