Why does a long bar help a tightrope walker to keep his or her balance?
Why does a long bar help a tightrope walker to keep his or her balance?

The tightrope walker uses the long bar to increase its rotational inertia. The increased rotational inertia makes it difficult for the gravitational force to turn the walker about its axis of rotation and in the meanwhile the walker gets enough time to restore its balance again.

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
