The Leaning Tower of Pisa does not fall because:
Explanation:
The Leaning Tower of Pisa is famous for its unintended tilt, which has been attracting tourists from all over the world. Despite its significant lean, the tower has managed to remain standing for centuries. The correct answer to why the tower does not fall is option 'D', which states that the vertical line through the center of gravity of the tower falls within the base. Let's explore this answer in more detail:
Center of Gravity:
The center of gravity is the point through which the entire weight of an object can be considered to act. In a symmetrical object, the center of gravity lies at the geometrical center. However, in an asymmetrical object like the Leaning Tower of Pisa, the center of gravity is shifted due to its tilt.
Effect of Tapering at the Top:
The tower is tapered at the top, which means it becomes narrower as it goes higher. This tapering helps in distributing the weight of the tower more evenly, reducing the stress on the lower parts. It prevents the tower from toppling over due to excessive weight at the higher levels.
Large Base Area:
The tower has a large base area, which provides stability and prevents it from tipping over. The weight of the tower is distributed over a larger surface area, reducing the pressure on the ground and maintaining its equilibrium.
Center of Gravity within the Base:
The most crucial factor that prevents the tower from falling is that the vertical line through the center of gravity of the tower falls within the base. This means that the imaginary line passing through the center of gravity always remains inside the footprint of the tower, ensuring its stability. If the center of gravity were to fall outside the base, the tower would lose its balance and topple over.
Conclusion:
The Leaning Tower of Pisa remains standing due to a combination of factors, including its tapered structure, large base area, and most importantly, the positioning of the center of gravity within the base. These factors work together to maintain the tower's equilibrium and prevent it from falling.
