When you read the web material for this lesson and e-book material for this lesson, use the following questions to guide your reading. Also, remember to keep the learning objectives listed on the Overview page in mind.

  • What is the difference between stress and strain?
  • Given a stress-strain diagram for material, how can one identify the elastic region, plastic region, fracture point, elasticity, and the yield strength?
  • Given a stress-strain diagram for a material, how can you determine if the material is ductile or brittle?
  • How do tensile, compressive, and shear stress differ?
  • Do the terms stiffness, strength, hardness, ductility, and toughness mean the same to the general public as they do to materials scientists and engineers?
