Part C $-$ Interpreting the data

You have built the majority of the tension testing machine, but much of the instrumentation is still being assembled. To test the machine, you perform a test on a steel specimen with known properties. The machine provides you with the given load data, and you manually record the lengths between the marks on the specimen at each point using an extensometer to obtain the table of data shown below.

Use these results to calculate the stress and strain at the yield point, the ultimate strength point, and the fracture point.

Express your answers to three significant figures.
