Objectives

Lesson outcomes

  • Describe deformation caused by tensile and compressive forces in one dimension.
  • Use the terms load, extension, compression, and limit of proportionality correctly.
  • Recall and apply Hooke's law for materials within the limit of proportionality.
  • Use k = F / x to calculate spring constant, force, or extension.
