A 4140 steel bar 2 feet in length and 0.5 inch in diameter is subjected to a test load, which is increased until the strain is 0.001. At this point the test load is 8200 lbf. Calculate the following for the bar:a) engineering stress at 0.001 (0.1%) strain, b) elongation, c) Young's modulus, d) final diameter of the bar Note: Poisson's ratio is 0.31 for 4140 steel, e) true stress, f) true strain.
