To measure the tensile properties of a steel requires you to extend the test piece at a fixed speed and continuously measure the extension as the applied force, or load increases, as you would expect from Hookes law up to the elastic limit and beyond.
From the load-elongation data you calculate the stress and strain as follows:
Stress = Load / Original Area of the test piece
Strain = Length / Original Length of the test piece
