Unit 7: Strength and Elasticity of the Body

Learner Objectives

  1. Identify and define the features of a stress-strain curve, including stress, strain, elastic region, elastic modulus, elastic limit, plastic region, ultimate strength, and fracture/rupture.[2]
  2. Acquire stress-strain data and calculate the elastic modulus from stress-strain data.[4]
  3. State Hooke’s Law and define spring constant.[3]
  4. Apply the Hooke’s Law along with the definitions of stress, strain, and elastic modulus to calculate the deformations of structures. [3]
