Try this first
Which of the following correctly defines the Young modulus?.
- A.Young modulus = Stress / Strain
- B.Young modulus = Strain / Stress
- C.Young modulus = Force / Area
- D.Young modulus = Area / Force
Model answer
What a good answer should say
- Young modulus = Stress / Strain
Explanation
Why this works
The Young modulus is defined as the ratio of tensile stress to tensile strain, providing a measure of a material's stiffness.
