The stress is the amount of deformation in the material, such as the change in length in an extensional experiment, expressed as a fraction of the beginning length. The strain is the force exerted on the sample divided by the cross-sectional area of the sample.
The definitions of stress and strain are switched around in this paragraph. Stress is the force on the sample divided by the area and strain is the deformation divided by the original length.
