Message: [QUOTE="NJCuse97, post: 3140991, member: 5058"] This is essentially correct save a term or two. I will try to come up with a simpler way to explain it if needed. It is essentially a push force and a pull force working together. The top cord of the truss (the whole thing is the crown truss) is essentially squeezing itself (compressive force, think of a vice) because of the pull of the roof hangers (tensile force, like you’ve got a fish on). The lean helps with the squeeze. The more squeeze, the less likely that ring will go anywhere, until the pull is just too much of course. That’s why the truss is so tall, (or deep). This is similar to MSG or the Pantheon in Rome. The whole roof (Dome?) is the crown truss and the hole is what we are hanging from. That hole is made by the top cord.
