Question | Answer |
---|---|
Elastic | After deformation will return to original shape |
Plastic | After deformation will not return to its original shape |
Elastic Limit | The force/change in x beyond which the material is permanently deformed |
Stiffness | F=k x change in extension |
Ductile | Can be pulled under a tensile force into a longer thinner shape |
Malleable | Can be deformed under comprression, 'hammerable' |
Strong | Requires a large force to break it |
Strength | the force/unit area required to break |
Brittle | Easily cracks with little deformation |
Tough | Deforms Plastically. Rerquires a large force for a small deformation |
Hard | Not readily scratched/ indented |
