the ability of solids to recover their original shape after being deformed by an external force
True of False: All solids have the property of elasticity.
term for the tendency to resist flexing or deforming
elastic limit
term for the point past which a material will not recover its original shape
term for the amount of deformation required to bring a material to its elastic limit
term for the maximum amount of relative deformation that may be permanently imposed upon a material
term for a large, solid bar of newly refined metal
mechanical working
term for the processes used to impose desired shapes upon ingots
term for two half-molds that enclose a desired shape when they are brought together
process that involves squeezing or pounding metal with great force between two dies
process that involves pressing down a metal by a series of paired, heavy rollers into a continuous sheet
the property of a metal that allows it to be rolled or hammered into a sheet
process in which metal is pulled through a single die into a continuous ribbon with the same cross-sectional shape as the interior surface of the die
the property of a metal that allows it to be drawn into wire
term for the attractive force between particles of the same kind
tensile force
term for the stretching or compressing force of the load
restorative force
term for the force that acts against the tensile force
Hooke's Law
law that states that the force of a wire pulling upward is proportional to its displacement downward, and that the restorative force acts in the opposite direction of the displacement
term for the deformative tensile force per unit cross-sectional area
stress = F/A
formula for stress
term for the relative amount of deformation-- or the ratio of change compared to the original length
tensile stress and tension
two terms for the effect due to pulling a rod along its length
Young's modulus
"Y" represents ____ _____.
Compression forces are always _____.
proportional limit
term for the point at which a wire's restorative force is no longer a linear function of elongation and Hook's law breaks down
elastic limit
term for the maximum stress a material can sustain without being permanently deformed
ultimate tensile strength
term for the maximum stress a material can sustain without brreaking
breaking point
term for the maximum strain tolerated by a wire
Objects that break suddenly under a load instead of deforming first are described as ____ objects.
term for the distance at which there is no net attraction or repulsion
term for the combination of two oppositely directed forces along parallel lines of action
The stress that causes bulk deformation is called ____ stress.
True or False: There is no elastic limit or ultimate strength for volume stress.
