That's not really the reason it is in tension. it is in tension because the lowest part of the top frame is below the highest part of the bottom frame, and one hangs from the other.
That’s true, but if it was all in tension it would accelerate off to infinity, the tension chain in the middle is connected to two cantilever arms. It’s a fun play on the mind in that chain is perceived to only work in tension, if you replace the chain with wood it’d be the same forces but wouldn’t elucidate the same feeling.That's not really the reason it is in tension. it is in tension because the lowest part of the top frame is below the highest part of the bottom frame, and one hangs from the other.
