A tension test was conducted on a specimen of AISI 1020 hot rolled steel having an initial diameter of 9.11 mm. The load at the 0.2% plastic strain offset was 17.21 kN, the highest load reached was 25.75 kN and the load at fracture was 17.39 kN. After fracture, the broken halves were assembled and the following measurements were made: (1) Marks on opposite sides of the necked region that were originally 25 mm apart had stretched to 38 mm apart. Similar marks originally 50 mm apart had stretched to 68.5 mm apart. (3) The final diameter was 5.28 mm. Determine the following properties from this test: yield stress, ultimate strength, percent elongation and percent reduction in area. Estimate the toughness.
