A steel bar with a 30 mm diameter is tested in tension. By monitoring the load reading of the testing machine, it was found that the specimen yielded at a load of 185 kN and fractured at 215 kN. Determine the tensile stresses at yield and at fracture. Estimate how much increase in length would occur at 70% of the yield stress in a 50 mm gauge length.
