Define tensile stress and tensile strain in the context of materials under tension.
Model answer
What a good answer should say
- Tensile stress is defined as the force applied per unit area of a material, calculated using the formula: tensile stress = F / A, where F is the force in newtons and A is the cross-sectional area in square meters.
- Tensile strain is the ratio of the change in length to the original length of the material, given by the formula: tensile strain = ΔL / L0, where ΔL is the change in length and L0 is the original length.
Explanation
Why this works
This question tests the understanding of fundamental concepts in material mechanics. A strong answer clearly defines both tensile stress and strain, providing the relevant formulas and explaining the physical significance of each term.
