>>1917867Can someone explain how this works to me? The structure, that is. The rings don't make sense to me.
The tension wires pull inwards on the rings. So that would keep the rings from bending out. But what keeps the rings from bending in? Is it that the rings are under compression from vectors at angles so that the net force on each ring segment is outward, which is then countered by the tension wires for equilibrium?
