If you can stretch a cable across a "chasm" chances are that you can pop an I-beam in there instead. That would solve that problem.

- pbhj 17y agoBecause I-beams are perfectly rigid and don't flex at all?? I'm guessing "would render that problem so small as to be unnoticeable" but maybe the pendulum is so light that effects are drowned by random noise or don't exist - there must be a potential well to climb out of before lateral forces cause axial flexing so I'm probably wrong.
