IRON OR STEEL?
The Eiffel Tower was built for the World Exhibition in 1889, held for the French Revolution in 1789. Gustave Eiffel was the brains behind the design of the Eiffel Tower. Emile Nouguier and Maurice Koechlin also worked on the designing of the Eiffel Tower. Around 50 engineers, 100 iron workers, and 121 construction workers worked on the Eiffel Tower.
It's Made Of
Lots of people believe that the Eiffel Tower is made of steel but in fact it is made of iron. Gustave Eiffel was an expert in the engineering use of structural iron and knew what it could and could not do, whereas steel was new for structural use. Gustave Eiffel was sure that using iron instead of any other material for the Eiffel Tower would be a great decision and would do everything he wanted and needed it to do.
Eiffel was criticised for the design of the Eiffel Tower and was accused of trying to create a piece of art, and didn’t worry about the engineering. But Eiffel and his engineers, however, as experienced builders, understood the importance of wind forces and knew that if they were going to build the tallest structure in the world they had to be certain it would withstand the wind. Eiffel designed the tower that shape so it could withstand the harsh wind forces, he made sure it could so many people to come could see the magnificence of the tallest structure in the world. It is the shape of a pyramid, you could say, because the base, square, of the shape would be strong and the shape going to a point so all the weight would be at the bottom and not the top so the tower would not fall over.
The Eiffel Tower cost $260,000 to construct. This might seem like a lot of money but now to build the tallest tower in the world it would cost way more money basically because everything they used to build the Eiffel Tower, including the engineers.
