What is the Young's modulus of copper?
Think it through first, then pick an option.
- a 50 G-Pa
- b 69 G-Pa
- c 117 G-Pa
- d 200 G-Pa
Answer and explanation
Correct answer: c 117 G-Pa
In Table 5.02 the Young's modulus of copper is 117 GPa.
Why the other options are wrong
- a 50 G-Pa: The 50 GPa is the lower end of the glass range (50-90) in the table, not copper.
- b 69 G-Pa: The 69 GPa is the value for aluminium in the table, not copper.
- d 200 G-Pa: The 200 GPa is the value for iron in the table, not copper.
