Question: A metal is deformed in a tension test into its plas-tic region. The starting specimen had a gage length 2.0 in and an area = 0.50 in2. At one point in the tensile test, the gage length = 2.5 in and the corresponding engineering stress = 24,000 lb/in2; at another point in the test prior to necking, the gage length = 3.2 in and the corresponding engineering stress = 28,000 lb/in2. Determine the strength coefficient and the strain-hardening exponent for this metal.
