Question

Hooke's law defines (a) stress (b) strain (c) modulus of elasticity (d) elastic limit

Answer 1

Answer:

(a)Stress

The force acting on unit area at the surface of a body is called stress .

stress = Force \ Area

(b) strain

A comparison of such a charge caused by the stress with the original length volume or shape is called as strain.

Strain = Change in length \ Original length

Hooke's law

The strain produce in a body by the stress applied to it is directly proportional to the stress with in the elastic limit of the body
