What is true of the class of solids called elastomers?
AThey follow Hooke law
BThey disobey Hooke law
CThey show no strain at all
DThey show no stress at all
Answer & Solution
Correct answer: B. They disobey Hooke law
1. Their stress strain curve is not a straight line over most of its range.
2. They also show no well defined plastic region.
3. So elastomers do not obey Hooke law.
