Prex, I am talking about the flange of a winch (quite a common application and I am surprised it's very hard to get information about calculating force on these flange), highest pressure on the drum (inner radius), 0 at the outer radius. Pressure is caused by the cables.
Interesting topic, just today I worked on a similar problem.
My load is an triangular pressure on a circular plate which is highest on the inner radius and 0 at outer radius.
I tried Roark to find a formula but there isn't one for the case I had. My workaround: I figured out an average...
