    So I believe that this would work fine when the middle person is being suspended, but I don’t think the physics work out when you’re dangling someone at the end.

    The person at the other end would need to be working their ass off to keep them from falling, the person in the middle would just be a fulcrum basically and wouldn’t be able to help much at all as the log spun in their hands.

    It would probably work with more than three people. I think it’s dicey with three, I think that if they all hold on they would all be going in the hole.

    I guess it would also depend on how long the log is. I think it might work with a log longer than the one in the image. I think the one in the image is too short to get sufficient leverage.

      The person in the middle would be supporting twice the weight of the person over the hole, and they would have to do it twice.
      The person over the hole and the person not over the hole just has to hang on.

      When the middle person is over the hole, the people at each end support half the weight of the person over the hole.

      The length of the pole doesn’t matter, as long as the person in the middle is in the middle of the pole and that the pole is more than twice the length of the hole.
      If the pole was significantly long enough, then the force on the middle person could be reduced significantly, but it will always be more than the weight of 1 person.
