A tensile test uses a test specimen that has a gage length of 50 mm and a radius of = 7.98 mm. During the test the specimen yields under a load of 98,000 N. The corresponding gage length = 50.23 mm. The maximum load of 168,000 N is reached at a gage length = 64.2 mm. Determine (a) yield strength (5 points), (b) modulus of elasticity (5 points), (c) ultimate tensile strength (5 points), (d) true yield strength (5 points), (e) true tensile strength (5 points), (f) strain hardening exponent (5 points), and (g) strength coefficient (5 points).
