shaped specimen is pulled in a
machine. During the test, the force F
needed to pull the specimen and the
length L of a gauge section are measured. This data is used for plotting a
stress-strain diagram of the material. Two definitions, engineering and true,
exist for stress and strain. The engineering stress

The following are measurements of force and gauge length from a ten-
sion test with an aluminum specimen. The specimen has a round cross sec-
tion with a radius of 0.25 in. (before the test). The initial gauge length is 0.5
in. Use the data to calculate and generate the engineering and true stress-
strain curves, both on the same plot. Label the axes and use a legend to
identify the curves.
