Study Notes
Elasticity
- Elasticity is the ability of a material to deform under stress and return to its original shape when the stress is removed.
- Materials that exhibit elastic behavior follow Hooke's Law.
- Hooke's Law states that stress is directly proportional to strain, within the elastic limit.
- The elastic limit is the point beyond which the material will not return to its original shape.
- Beyond the elastic limit, the material enters the plastic region.
- Elasticity is a crucial property in many engineering applications.
- Different materials exhibit varying degrees of elasticity, influenced by their structure and composition.
- Factors such as temperature and pressure can impact a material's elastic properties.
