2. The modulus of elasticity, or Young’s modulus, is computed by calculating the slope of a stress-strain diagram over the elastic region.
3. The modulus of elasticity is a measure of how easily a material will stretch when pulled (subject to a tensile force) or how well the material will shorten when pushed (subject to a compressive force).
4. A ductile material shows little or no permanent deformation before it ruptures.
5. A brittle material, when subjected to a tensile load, will go through significant permanent deformation before it breaks.
