Why Do Tightrope Walkers Carry A Pole/Bar During Their ...

Carrying a balancing pole increases the moment of inertia (rotational inertia) of the tightrope walker. By carrying a pole (it's called a balancing pole, more specifically) horizontally in their hands, the tightrope walker increases his moment of inertia, i.e., he minimizes his body's "rotation" around the rope.

Why do tightrope walkers carry a pole? How does the pole ...

Answer (1 of 3): In short, viewing this in terms of rotational motion of walker about the axis of the rope (see diagrams below), the long pole is increasing the overall `moment of inertia' I of the walker, whilst the `torque' tau (when walker loses balance) remains the same. This is analogous to...

The impact force depends on the weight of the climber, the rope stiffness, and the ratio of the rope length to the fall height. This ratio,, Eq(3) has become known as a "fall factor". Based on the a bove formulation, a fall of 20 ft. on 100 ft. of rope should generate …

How Much Weight Does a Pulley Take Off? | Sciencing

Suspend a third pulley from the first, loop the rope through that so three ropes are suspending the load, and the force you have to exert to lift the load is only one-third of its weight. You could say, in general, that the pulley load reduction is the reciprocal of the number of ropes supporting the load, but few practical pulley systems have ...
