Caught on the knot

The pendulum must be able to swing smoothly and freely in a circle, without jerking or getting caught on the knot in the string or the attachment to the chain.

--- Does it mean that the string and the chain cannot get tangled?
  

Top answer

No, it doesn't actually say that (though I imagine that is also true). The pendulum must not get caught on the knot in the string. The pendulum must also not get caught on the attachment to the chain.

Is "pendulum" here the heavy part at the end of the string or chain? For example a stone hanging from a string?

What sort of device is being described? Is it a clock?

No, it's a pendulum that you use to find out something, to get the answer, like in magic.

Oh, OK, I assumed that the pendulum was rigid and separate from the string and chain. It isn't possible to be certain of the configuration just from that one sentence. You need more explanation or a diagram.
