A No. 10 steel rebar is tested in tension. By monitoring the load reading of the testing machine, it was found that the specimen yielded at a load of 41,600 lb and fractured at 48,300 lb.a. Determine the tensile stresses at yield and at fracture.b. Estimate how much increase in length would occur at 70% of the yield stress in a 2-in. gauge length.
