A circular steel specimen with an initial dimeter (do) of 6.1 mm and a gauge length (lo) of 35 mm is deformed in tension using strain rate of 0.05mm/s. The final diameter, df = 4.0 mm, is measured. Use the load - elongation experimental data shown in table to complete parts a) Load, Elongation through f). a) Plot data as engineering stress versus engineering strain. Please, use the Excel. (Show the graph on a separate sheet or copy on the bottom.) b) Determine the yield strength (value here) 11750 1.5 11500 1.625 12000 1.75 14250 2.5 15250 3 16000 3.5 16750 4.25 17250 5 17500 6.625 c) What is the modulus of elasticity of this steel?
