The Eiffel Tower, which is made entirely of metal, can
stretch up to 15 cm, due to the summer heat,
which may disrupt the balance of the tower. How
could engineer Gustave Eiffel solve this problem?
Answers
Answer:
One of the reasons the Eiffel Tower is still as dazzling as ever is because it adapts to its environment and all types of weather conditions: wind, cold, rain, snow, frost, heat, etc. Like any metal, puddled iron is sensitive to variations in temperature and so reacts to high temperatures in summer and low or even negative temperatures in winter.
When temperatures rise, the Tower increases in size! This is a natural physical phenomenon called thermal expansion. Heat causes an increase in volume that makes the Eiffel Tower a few centimeters taller. This expansion also causes the Tower to tilt slightly away from the sun. The sun only hits one of the 4 sides of the Tower creating an imbalance with the other 3 sides, that remain stable, thus causing the Eiffel Tower to lean. In this way, the sun’s movement over the course of a clear day can cause the top of the Tower to move in a more or less circular curve measuring approximately 15 centimeters in diameter.
