Rotational Intertia and Angular Acceleration while Tightrope Walking

If you look at pictures of tightrope walkers, you will also see that their arms are spread out or they have a long balancing pole. This is to increase the rotational inertia and reduce angular accelerations of the walker. A walker will need this when he/she is walking and may become unbalanced. They will adjust their arms or the pole so that the torque on the body is equal and opposite of that on the pole.
