Eiffel Tower in Paris
Named after its designer, engineer Gistave Eiffel., the Eiffel Tower is the tallest building in Paris and More than 200,000,000 have visited the tower since its construction in 1889, making it the most visited paid monument in the world. Including the 24 m (79 ft) antenna, the structure is 325 m (1,063 ft) high (since 2000
The metal structure of the Eiffel Tower weighs 7,300 tonnes while the entire structure including non-metal components is approximately 10,000 tonnes. Depending on the ambient temperature, the top of the tower may shift away from the sun by up to 18 cm (7 in) because of thermal expansion of the metal on the side facing the sun. The tower also sways 6-7 cm (2-3 in) in the wind.As demonstration of the economy of design, if the 7300 tonnes of the metal structure were melted down it would fill the 125 meter square base to a depth of only 6 cm (2.36 in), assuming a density of the metal to be 7.8 tonnes per cubic meter. The tower has a mass less than the mass of the air contained in a cylinder of the same dimensions, that is 324 meters high and 88.3 meters in radius. The weight of the tower is 10,100 tonnes compared to 10,265 tonnes of air.
So , I hope to went and visit to the Eiffel Tower because it is the tallest building in Paris .
And top building in the world.
