Even though the Tower of Pisa is leaning through an angle it does not fall.

उत्तर
Leaning tower of Pisa is stable because a line through the centre of gravity falls within the structure's base. If the line falls outside the structure's base then there is a possibility that overturning will occur. This structure could be classified as unstable.
