Are you saying that when the surfaces end at the same height the angle of the first slope will allways cancell out the size of the chain on the second slope?

So none of these would move?

Because that was whut i was thinking...
That's what the maths says :)

Yep, a round chain wouldn't move in any situation. However when the surfaces end at the same height then there's no net force on the green part below, therefore if there's a net force on the red (top) part, then it would cause it to move. Given that, and since we know the linked chain won't move on its own there must therefore be no net force on the top (red) part.
I think that's what Cookie is trying to say anyway.

Thanks for the translation Volv. That was turning my brain to mush.
