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.
A television antenna was first installed on the tower in 1957, increasing its height by 18.7 m (61.4 ft). Work carried out in 2000 added a further 5.3 m (17.4 ft), giving the current height of 324 m (1,063 ft). Analogue television signals from the Eiffel Tower ceased on 8 March 2011.
