This article reviews the composition, structure, and properties of man-made fibres, both regenerated and synthetic, and then describes the ways in which they are spun, drawn, and textured into useful fibres.
To complete the analysis both the safety and the efficiency of the design are evaluated. Eiffel designed the Tower to be 300 meters high, which is 984 feet (approximately 90 stories); it is 328 feet wide at its base. This dimension quickly tapers as illustrated by the following diagram and chart.
The tower received its 250 millionth visitor in 2010. The tower is 324 metres (1,063 ft) tall, about the same height as an 81-storey building. Its base is square, 125 metres (410 ft) on a side.During its construction, the Eiffel Tower surpassed the Washington Monument to assume the title of the tallest man-made structure in the world, a title it held for 41 years, until the Chrysler Building in New York City was built in 1930.ecause of the addition of the aerial atop the Eiffel Tower in 1957, it is now taller than the Chrysler Building by 5.2 metres (17 ft). Not including broadcast aerials, it is the second-tallest structure in France, after the Millau Viaduct.
