Скачать или смотреть Eiffel Tower Grows 15 cm in Summer?! Thermal Expansion

The Eiffel Tower can be 15 cm taller during the summer due to thermal expansion. The Eiffel Tower's summer growth is a classic example of thermal expansion. As the 7,300 tons of iron latticework heat up, the metal particles vibrate more intensely, causing the entire structure to expand. The effect isn't uniform; the side of the tower facing the sun absorbs more heat than the shaded side. This temperature difference causes the tower to lean slightly away from the sun, with engineers noting the top can trace a circular path roughly 15 centimeters in diameter throughout the day. This constant, subtle movement was anticipated in its original 1889 design, a testament to the engineering foresight required to manage Paris's fluctuating temperatures.
