1, the construction of the tower body of each stone brick is a piece of stone carving masterpiece, stone brick and stone brick bonding is extremely clever, effectively preventing the tower body tilt caused by the fracture, the leaning tower slanting and does not fall of a factor.

2, the tower's center of gravity falls in the center of the projection of the foundation, you can ensure that gravity is perpendicular to the ground, which is the Leaning Tower of Pisa does not fall down the biggest reason.

Gravity acts on every position of an object, but this is not good for force analysis. So we combine all the effects of gravity into one force acting at one point that is equivalent to the combined force of all gravity forces. The point at which this force acts is the center of gravity.

The location of the center of gravity of an object with a uniformly distributed mass (a homogeneous object), the location of the center of gravity is related only to the shape of the object. An object with a regular shape has its center of gravity right at the geometric center.
