3. The plot below of load vs. extension was obtained using a specimen (shown in the following figure) of an aluminum alloy. The crosshead speed was V = 3.3x10-4 inch/second. The extension was measured using a 2" extensometer as shown (G). Eight points on the plastic part of the curve have been digitized for you. Use these points to help answer the following questions. 900 Load, pounds 800 700 (0.10, 630) 600 (0.30, 729) (0.50, 745) (0.20, 699) (0.40, 741.5) 500- (0.004,458) 400 (0.0018, 405) 300 200- 100 100 (0.80, 440) D=3.3" 0.03" G-2.0" 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 80 Extension, inches A) Determine the following quantities. Do not neglect to include proper units in your answer. a. Yield stress, σy b. Young's Modulus, E c. Ultimate tensile strength, OUTS d. Total elongation, @total e. Uniform elongation, uniform f. Post-uniform elongation, total uniform g. Engineering strain rate, &=V/D
