Question

8. Define (a) stress and (b) strain. Write Hooke's Law of flasticity A metal wire hangs from a base ! Hanging its free and is gradually its behaviour with the help of a nominated the on increased! So describe its behaviour with the help of a nominated stress-sales graph?​

Answer 1

Hooke’s Law states that for small deformities, the stress and strain are proportional to each other. Thus,

Stress ∝ Strain

Or, Stress = k × Strain … where k is the constant of proportionality and is the Modulus of Elasticity. It is important to note that Hooke’s Law is valid for most materials.
