[16] M. A. Ansaloni, “The Lifts in the Eiffel Tower,” quoted in Engineering, July 5, 1889, vol. 48, p. 23. The strength of steel when drawn into wire is increased tremendously. Breaking stresses of 140,000 p.s.i. were not particularly high at the time. Special cables with breaking stresses of up to 370,000 p.s.i. were available.
