Questions and Answers

What is the true strain of a steel rod that has been stretched from 10 inches to 10.18 inches?

  • 0.018 (correct)
  • -4.017
  • 1.018
  • 0.01784

    • What is the purpose of the quick quiz in Figure 4?

  • To compare the engineering stress-strain curve with the true stress-strain curve.
  • To identify the type of material being tested.
  • To determine the modulus of elasticity of the material.
  • To calculate the true strain of a steel rod. (correct)

    • What is the difference between the engineering stress-strain curve and the true stress-strain curve?

  • The engineering curve is used for compression, while the true curve is used for tension.
  • The engineering curve is for brittle materials, while the true curve is for ductile materials.
  • The engineering curve is based on the original dimensions of the material, while the true curve is based on the instantaneous dimensions. (correct)
  • The true curve is a measure of the material's strength, while the engineering curve is a measure of its toughness.
