Chapter 11, Problem 11A

To determine

The reason that the Leaning Tower of Pisa does not topple.

Explanation of Solution

Introduction:

The center of gravity is the point where whole weight of a body is hypothetically concentrated. It is also called balance point since at this point, object would balance.

To keep object upright, the center of gravity of an object should be above the area of support. When the center of gravity goes outside the area, the object will topple. The tower of Pisa will not topple since its center of gravity does not go outside the area of support. It is above the base of tower.

Conclusion:

The center of gravity of tower lies inside the area of support due to which tower will not topple.
