The following data were recorded during tensile test of 14 mm diameter mild steel rod. The strain gage length was 50 mm. Plot the stress-strain diagram and determine the following mechanical properties: a. Proportional limit = b. Modulus of elasticity, Eσ/E, slope before yielding c. Yield Stress GRIP SECTION WIDTH OF GRIP SECTION OVERALL LENGTH DISTANCE BETWEEN SHOULDERS GAGE LENGTH DIA. OR WIDTH "REDUCED" SECTION d. Ultimate Stress e.
