Restoring force
|
Force that restores a system to an equilibrium poison
|
|
|
Elastic
|
Systems that exhibit restoring forces are called this
|
|
|
Equilibrium length
|
When no forces are acting on a spring to compress or extend it. It is the relaxed spring length
|
|
|
Graph of spring force
|
The magnitude of restoring force is proportional to the displacement of the spring from equilbrium.
Stretching or compressing the spring twice as hard, would result in a resulting force that is twice as large. |
|
|
Spring constant
|
k. It's unit is N/m SlOp
Property that characterises a particle. If k is large, it takes a large pull to cause significant stretch. "stiff" If k is small, it takes small pull to cause significant stretch "soft" |
|
|
Rigid vs pliant
|
Rigid: very high k constant
Pliant: low k constant |
|
|
Tensile stress
|
Stress in due to stretching.
Strain is fractional change in rod's length, so if rod's length changes by 1%, strain is .01 |
