In mechanics and physics, Hooke's law of elasticity is an approximation that states that the extension of a spring is in direct proportion with the load applied to it. Many materials obey this la [..]

Below the elastic limit, strain is directly proportional to stress.

an approximation that states that the extension of a spring is in direct proportion with the load added to it as long as this load does not exceed the elastic limit.

The stress applied to any solid is proportional to the strain it produces within the elastic limit for that solid. The constant of that proportionality is the Young modulus of elasticity for that substance.

(physics) the principle that the stress applied to a solid is directly proportional to the strain produced. This law describes the behavior of springs and solids stressed within their elastic limit.

The linear relationship of forces and deformations, or stresses and strains.

The principle that the stress within a solid is proportional to the strain. It holds only for strains of a few percent or less.

The linear relationship of forces and deformations, or stresses and strains.

Within the elastic limit, a strain is proportional to the stress producing it.
