Definitions for "Hooke's Law"
Suppose denotes a spring exerting a force on a load, and denotes the position of where the position at which the force exerted by on b is taken to be zero. Then F=-kx, according to Hooke’s Law
This states that, “within the limits of elasticity the strain produced by a stress of any one kind is proportional to the stress.” The stress at which a material ceases to obey Hooke's Law is known as the Limit of Proportionality.
The principle that the stress within a solid is proportional to the strain. It holds only for strains of a few percent or less.
