My cylinder has an original length of I o and surface area of A o. As I pull on my material with the force F the cylinder will lengthen and the resulting length will be l. Stress, σ, is defined as the force divided by the initial surface area, σ=F/A o. This pulling stress is called tensile stress. Strain is what results from this stress.
