# explain why a long pole is more benefiacial to a tightrope walker if the pole droops?

Relevance

It's all in the balance and the weight. A longer pole provides more stability for those reasons. Think of it this way. At your now given height, if your arms were only a foot long, could you balance yourself while say walking on top of a narrow wall? or is it easier to do with your arms at their normal length? the poles are made to be flexible and not rigid so that they flex and the walker can adjust the pole while walking. Better center of gravity.

Tightrope Balance Pole

Have you ever seen an ice skater twirl? She starts with her arms out wide and spinning slowly. As she slowly brings her arms in toward her chest she rotates faster. That's because as she brings her arms in her moment of inertia (aka rotational inertia, the rotational analog to mass) decreases. The same principle applies in the case of the tightrope walker, except that the pole is much longer than the arms of the ice skater. With a much larger moment of inertia the tightrope walker won't rotate off the rope very quickly, giving him a chance to compensate before it is too late.

Longer poles put more weight out where it can be more easily manipulated. A slight shift of a long pole can result in much more weight balancing than the same amount of shift in a short pole. With a long pole the "balancing" of the tightrope walker is almost automatic and all the walker has to pay attention to is placing his or her feet.

Stability is tied to the location of the center of mass above the rope. A long, droopy pole effectively lowers the center of mass for the system, thereby making it more stable.

Drooping pole, longer pole, lower center of gravity, basic physics.

It lowers the center of gravity making it easier for the walker to keep his balance.

the reason for this is that the line joining the centre of gravity and centre of equilibrium must fall within the rope for for acheiving the stable equalibrium
