Why doesn’t the Leaning Tower of Pisa fall?

Why doesn’t the Leaning Tower of Pisa fall? Even leaning, the Leaning Tower of Pisa, which was built between 1178 and 1370 in Italy, does not fall. Physics explains this occurrence!

Due to the type of balance, the Leaning Tower of Pisa does not fall
The Leaning Tower of Pisa doesn’t fall because its balance type is stable. With the tilt, its center of gravity (the region where most of the weight is concentrated) occupies a higher position in the tower, which generates a torque that prevents it from falling. If the angle of inclination continued to increase, there would come a time when the center of gravity would no longer coincide with the base of the tower, and then the tower would fall.

Tower Tilt

In 1178, during the construction phase, the tower began to lean and, in 1370, when it was inaugurated, it already had 1.6° of inclination, which caused the top of the tower to be 1 m from the position where it should have been. be.

The reason for the slope was the swampy and unstable ground where the tower was built. The tower’s mass of over 14,000 tons forced the fragile terrain, which resulted in the tower tilting.

In 1997, engineers were able to reduce the tilt to approximately 4°, which keeps the top of the tower within 4 m of where it should be. In addition to reducing the slope, work was done to stop the process from continuing. Thus, after a long period closed to visitors, the Leaning Tower of Pisa was reopened in 2003. 

General information about the Leaning Tower of Pisa

The Leaning Tower of Pisa is made of marble and is about 55 m high, not counting the foundation. It was built in the central square of the city of Pisa, Italy. Its construction began in 1173 and was completed only in 1370 due to problems with the slope.
