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 Eiffel Tower is 320 metres (1050 feet) in height and was the tallest man made structure in the world for 41 years before being surpassed by the Chrysler Building in New York. The Eiffel Tower is made of iron and weighs around 10000 tonnes. Around 50 tonnes of paint are added to the Eiffel Tower every 7 years to protect it from rust. Despite its height, the Eiffel Tower was designed to be wind resistant, swaying only a few inches in the wind. It actually moves further when the iron on the sun facing side heats and expands, moving the top up to 7 inches (18 centimetres) away from the sun.
