• change in proportion to its shape

• will change shape when the forces deforming it are removed

What does the blue arrow show?

• Elastic deformation

• Inelastic deformation

• Elastic limit

• Limit of proportionality

What does the red arrow show?

• Elastic deformation

• Inelastic deformation
