Lesson 02

Average Normal Strain

Learning outcomes

Statics Review:
  • Explain the relationship between deformation and force in a spring.
  • Recall that “fixed planes” may not translate (they are constrained) and that “free planes” may translate (they are unconstrained).
This Course:
    1. Explain the concepts of elongation and shortening.
    2. Understand similarities between deformation in a spring and in a solid bar.
    3. Differentiate between translation and deformation.
    4. Memorize and apply the definition of axial deformation.
    5. Understand and apply the equation for average normal strain.
