What to Focus On
- Deforming force produces deformation.
- Elasticity is the ability to regain original shape and size after force removal.
- Perfectly elastic, perfectly plastic, and rigid are idealised categories.
- Stress is force per unit area.
- Strain is unitless because it is a ratio.
- Hooke's law is valid for small strain.
- O to A is the linear region.
- Elastic limit is at B.
- Yield point is C.
Common Mistakes to Avoid
Stress and strain mean the same thing.
Elastic limit and limit of proportionality are the same point on the stress-strain graph.
Hooke's law is valid for all deformation.
