The three ways in which materials respond to forces:
1.Tension,
2.Compression,
3.Bending.
Explanation:
Tension- The force that is exerted when physical objects come in contact with each other.
Compression- Compression is the application of balanced inward ("pushing") forces to different points on a material or structure.
Bending- A bending force is a force that is applied to a length of material.
