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