Terms | Definitions |
|---|---|
 Elasticity | the ability to recover their original shape after being deformed by an external force |
| Rigidity | the tendency to resist flexing or deforming |
| Resilience | the amount of deformation required to bring a material to its elastic limit |
| Elastic limit | the point past which a material will not recover its original shape |
| Plasticity | the maximum amount of relative deformation that may be permanently imposed upon it |
| Mechanical working | the various processes used to impose desired shapes upon ingots of newly refined metal |
| Forging | metal squeezed or pounded with great force between two dies |
| Rolling | metal pressed down by a series of paired, heavy rollers into a continuous sheets |
| Malleability | the property of a metal that allows it to be rolled or hammered into a sheet |
| Tensile force | the stretching or compressing force of the load |
| Hooke's law | the force of the wire pulling upward is proportional to its displacement downward and that the restorative force acts in the opposite direction of the displacement; F=kx |
| Restorative force | the force acting against the tensile force |
| Stress | the deformative tensile force per unit cross-sectional area |
| Strain | the relative amount of deformation compared to the original length |
| Tensile stress | tension |
| Young's Modulus | the proportionality constant; F/A=Y(l/l) |
| Proportional limit | the restorative force in the wire is no linger a linear function of elongation |
| Elastic limit | the maximum stress the material can sustain without being permanently deformed |
| Ultimate tensile strength | the maximum stress the material can sustain without breaking |
| Breaking point | represents the maximum strain tolerated by the wire; further stretching causes the wire to break |
| Brittle | substances that break suddenly under a load instead of deforming first |
| equilibrium | the distance where there is no net attraction or repulsion; represents the standard relative positions when the particles are stable and unstressed |
| Shear | the combination of two oppositely directed forces along parallel lines of action |
| Volume stress | stress that causes bulk deformation |
