Why Do Tightrope Walkers Carry Long Poles when Walking on A Rope?
Carrying a pole helps the walker increase their rotational inertia, which aids in maintaining stability while walking over the narrow rope. The pole also adds more weight below the center of gravity of the walker, which is another bonus...
