3. A tensile test of a steel specimen produces the following data. The gage length is 2 inches and the diameter of the specimen is 0.505 inches. The specimen yield load is 7,200 pounds. The necking begins at 10,400 pounds. (a) From the data in Table, determine the true strain and true stress at necking. (b) Determine the value of the constant, K, in the true stress-true strain relation for the plastic region, o= Ke”. (c) Determine doldɛ at the maximum load.
