Elasticity and Hooke's Law

what is the meaning of elasticity?

• It is the force applied to a material, divided by the material’s cross-sectional area

• the material of a maerial stretched, and it stays stretched after removal of deforming force

• The property of a material to regain it's original shape and size after removal of deforming forces

• It is the ratio of the change in size or shape to the original size or shape.

what the hooke's law stated?

• the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance

• The material of a maerial stretched, and it stays stretched after removal of deforming force

• the ratio of the change in size or shape to the original size or shape

• measurement of stress over strain

force applied to a material, divided by the material’s cross-sectional area is

• stress

• strain

• plasticity
