What is the importance of Eiffel Tower?

Answer 1

Eiffel realised that the height of the tower could be utilised as an observatory. In 1889, he started using the peak of the tower as an observation station for the measurement of the wind speed. Other scientists also conducted experiments at the tower. Subsequent to experimentation in the sphere of meteorology, Eiffel began to observe the relationship and the effects of wind and air resistance. This science was later on classified as aerodynamics, which has now become an essential part of military and commercial aviation as well as rocket technology. In 1910, Gustave Eiffel achieved extraordinary results in measuring the wind resistance of a flat plate by using the Eiffel Tower as a test platform. To overcome the lack of available measuring instruments, Eiffel proceeded on to a quest for more sophisticated knowledge of aviation which ultimately led to wind tunnel experiments. In order to safeguard the tower from wear and tear, huge maintenance work is essential. This programme includes applying 50 to 60 tonnes of three graded tones of paint once every seven years to protect against rust. At each occasion when it is required to paint, the shade of paint is changed. Currently, the tower is painted with a shade of brownish-grey - the darkest layer is painted on the top which gets lighter towards the bottom. The Eiffel Tower has played a role in communication since the first decade of the preceding century. French radio, though regular transmission was started in 1922, maintained an aerial on the tower, and began transmissions from the tower in 1918. For FM (Frequency Modulation) and TV transmission, the Eiffel Tower has been an important platform since 1957. Lee de Forest, a French engineer and scientist who wanted to pioneer wireless telephony, broadcasted a phonograph record show from the Eiffel Tower on January 12, 1908, for an audience of less than 50 people; the show was heard over 500 miles from the tower. This occasion is marked as the first ever experience of long-distance radio message transmission. Eiffel Tower also has the distinction of being an active part of the first transatlantic and transcontinental radio telephone call. On October 21, 1915, radiotelephone communication was made between Naval radio station NAA at Arlington, Virginia and the Eiffel Tower.

Answer 2

the Eiffel tower is important because people like to go and visit it and its been famous for many years.
