Force and materials:
- A material is elastic if it returns to its original shape and size when the force is removed.
- A material is plastic if it doesn't return to its original shape and size when the force is removed.
Most materials are elastic for a certain range of forces - up to the elastic limit. Beyond this limit, they're plastic.
Hooke's law states that the extension, x, of a sample of material is proportional to the stretching force, F. x ∝ F. This can be reinterpreted as F = kx, where k represents…
