The enclоsed figure shоws the dimensiоns of а tensile test specimen of а metаl alloy, before and after a tensile test. The specimen cross-section stayed round through the test. The maximum force recorded during the test was 12,500 lbf. Plastic deformation was first observed when the force reached 8,200 lbf. Calculate the yield strength in psi.
