alleryFor small deformations, stress and strain stay proportional to each other. This result is known as what?
APoisson law
BPascal law
CHooke law
DNewton law
Answer & Solution
Correct answer: C. Hooke law
1. The relation holds only while the deformation stays small.
2. Within that range a graph of stress against strain is a straight line.
3. This proportionality is known as Hooke law.
