Question:

The elastic portion of the stress€“strain diagram for an aluminum alloy is shown in the figure. The specimen from which it was obtained has an original diameter of 12.7 mm and a gage length of 50.8 mm. When the applied load on the specimen is 50 kN, the diameter is 12.67494 mm. Determine Poisson€™s ratio for the material.

(MPa) 490 (mm/mm) 0.007
