Exam-style question
Try this first
Which of the following statements is true about the Young modulus of a material?.
- A.It increases as the material becomes more ductile.
- B.It decreases as the material becomes more brittle.
- C.It is independent of the material’s temperature.
- D.It is the same for all metals at room temperature.
Model answer
What a good answer should say
- It decreases as the material becomes more brittle.
Explanation
Why this works
A higher Young modulus indicates a stiffer, less ductile material. Brittle materials typically have lower Young moduli compared to ductile ones, reflecting their lower resistance to elastic deformation.
