Question

The tensile test was conducted on a specimen with a diameter of 0.5 inch. A strain gage was bonded to the specimen so that the strain could be obtained directly. The following data were obtained.

a) create a table of stress and strain values.

Plot this data points and draw the best fit straight line through them.

b) what is the slope of this line? What does this value represent?
