Metals have large Young's moduli, so they need a large force to produce a:
ASmall change in length
BLarge change in length
CChange in their colour
DChange in their mass
Answer & Solution
Correct answer: A. Small change in length
1. Young's modulus is stress over strain.
2. A large modulus means lots of stress for little strain.
3. So a big force gives only a small change in length.
