The Hooke's law is valid for
A). Only proportional region of the stress strain curve
B). Entire elastic region of the stress strain curve
C). Entire elastic region of the stress strain curve
D). Elastic as well as plastic region of the stress strain curve
Only proportional region of the stress strain curve
The Hooke's law is valid only when the stress is proportional to the strain, that is only in the proportionality limit.
