4. How materials respond when loads are placed upon them Stress and strain curve Elastic deformation Plastic deformation

7. Stress is the Force divided by cross sectional area Strain is the distance divided by the initial distance

8. Elastic Plastic Yield Point Slope in the elastic region is Young’s Modulus

9.  Can’t measure stress directly  Measure strain then read the stress off the stress-strain graph  Measure the strain by measuring the positions of the atoms with and without the stress

10.  …Crystal Lattices
