Question: The data shown in the table were obtained from a tensile test of a metal specimen with a diameter of 0.500 inch and a gage length (the length over which the elongation is measured) of 2.00 inches. The specimen was not loaded to failure.
a. Generate a table of stress and strain values.
b. Plot these values and draw a best-fit line to obtain a stress–strain curve.
c. Use the slope of the best-fit line to estimate the modulus of elasticity.
d. Estimate the value of the proportional limit.
e. Use the 0.2% offset method to determine the yield strength.
