Chapter 11, Problem 31A

Explain why a long pole is more beneficial to a tightrope walker if the pole droops.

To determine

To explain: A reason for a longer pole being favorable to a tightrope walker if the pole droops.

Answer to Problem 31A

Because it provides more stability and it is easier to balance the weight and provides a better center of gravity.

Explanation of Solution

Introduction:

To walk, a person needs to maintain its center of gravity and should be stable enough to counteract the gravitational force acting downwards.

Walking on the tightrope between 2 long poles, requires the same stability and center of gravity. As the rope is too narrow thus stability can be disturbed anytime. But, using long poles provides a longer span for the walker to counteract gravitational force from falling down and also maintain its center of gravity. Flexible poles help tightrope walker to adjust himself on the pole while walking along.

Conclusion:

Thus, due to more stability and better center of gravity, it is easier to balance the weight using long poles.
