Elasticity is the ability of a material to return to its original shape and size after a force is removed. Elastic materials are materials that can return to their original shape after being stretched by an external force. The elastic limit of a material is the maximum stress that can be applied to it without causing permanent deformation. If a material is stressed below its elastic limit, it will return to its original length once the stress is removed. The elastic limit is the point on a stress-strain curve beyond which the material cannot return to its original shape when the stress is...

The unit of elastic limit is Pascal or \(n/m^{2}\) Hooke's law, discovered by Sir Robert Hooke around the mid-17th century, states that for minute deformation, the applied deforming force is directly proportional to the displacement produced. It can be mathematically expressed as, F∝x. F=−kx. Stress is the force applied to a material per unit area. Strain is the deformation or change in the shape of the material that results from the applied force. For example, when you pull on a rubber band, it stretches. The deformation is a measure of how much the rubber band is stretched, and the strain is the ratio between the deformation and the original length. Show less
