Why doesn't the Leaning Tower of Pisa fall over?
The inclination of the tower slowed down during the following centuries, it is believed that its weight was an important factor allowing a certain stabilization of the building. The architect Alessandro Gherardesca made the first restoration in eliminating the muddy soil and replacing it with a marble base. The result was tremendous, this provoked a new tilt and in the Plumbing deviation reached 5. Holding an object by its center of mass keeps it in perfect equilibrium as gravity acts with the same torque in any direction around that point.
While this concept comes handy when you are in school studying physics or if you want to impress your friends balancing a knife on your finger it has little or no use in everyday life.
An object stands until the line drawn from its center of gravity to ground falls within its base. When talking about the Leaning Tower of Pisa, the concept of center of gravity comes to be very important. Any object that stands typically on its base will keep standing or falling back onto its base until the line drawn from its center of gravity to the ground falls within its base see image on the right. The mass of the Leaning Tower is about metric tons and, given its geometry thin at the top and thick at the bottom , its center of mass sits somewhere lower than the top of its 4th floor.
He successfully demonstrated that the mass of an object has no influence on the speed he gathers while falling towards the ground. In the Tower was leaning much less than today and its offset to the ground was surely not 4 meters. However, it was enough for Galileo to carry on his experiments and write an important page of history and science.
Galileo used the Tower to prove that mass of falling objects has no influence on their speed. Free download.
