portion of the curve to thevertical initial line measures the stiff-ness within the elastic limit or coeffi-cient of elasticity. This method ofrepresenting results—which is nowused by all scientific experimenters on the strength of materials —may either be plotted as above described from the data… … 240 320 200 THERMOMETER. 875 that of zinc. The concave form at the commencement indicates its inelastic nature, its slight alti-tude shows its weakness, and, breaking at 65°, it is shown to lack ductility. Tin, T, is vastlymore ductile, but is still less tenacious. B and C are the diagrams given by…
