Question details

Q2. A 2024-T4 Aluminum test specimen with a diameter of O S05 in and a 20 in. gage length was tested to fracture a tensile test. Load and deformation data obtained during the test are given. Determine (a) The modulus of elasticity (b) The proportional limit (c) The ultimate strength (d) The yield strength (005% offset) (c) The yield strength (0.20% offset) (0 The fracture stress (g) The true fracture stress if the diameter of the specimen at the location of fracture was 0.452 irn Load (Ib) Change in Length (x0.001 in.) 1300 2390 3470 4560 5640 6720 7380 8240 8890 9330 9980 10200 10630 11060 11500 12360 12580 12800 13020 13230 13450 13670 13880 14100 14100 14100 141 14100 3.2 5.1 6.0 7.0 79 8.8 9.7 10.7 12.5 13.9 16.2 27.8 39.4 78.8 97.4 115.9 139 1 1994 3200 324
