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.
1 The tower was built to sway slightly in the wind, but the sun affects the tower more. As the sun-facing side of the tower heats up, the top moves as much as 7 inches (18 centimeters) away from the sun. 2  The sun also causes the tower to grow about 6 inches.  The Eiffel Tower weighs 10,000 tons.
