## Round chain on the corner

Some people like to twirl a round chain on a finger.

I like to "twirl" a round chain on... a cone

on two nails

and on one... corner.
Can you determine (numerical or symbolical - better with Mathcad and without friction) the critical value of the alpha angle when the chain falls off the corner?

You can determinate this angle so too

One try of solution in attach! But I am not sure - is it correct!

I feel it is a solution - a numerical solution. Check please Mathcad 15 sheet in attach.

I am waiting for one symbolical solution. What is it 108-109 deg?

This angle is equal 2*50.34 deg. I hope in is equal n/m Pi. n and m -?
