Data was collected by hanging weights (F) on a metal wire and measuring the extension (x). The wire was originally 2.00 m long and had a cross-sectional area of 2.00 x 10⁻⁷ m².

The data shown in Table 2 was collected by hanging weights (F) on a metal wire and measuring the extension (x) caused. The wire was originally 2.00 m long and had a cross-sectional area of 2.00 x 10⁻⁷ m².
