Materials Flashcards
1
Q
What is Hooke’s Law?
A
The extension is proportional to the force applied provided the limit of proportionality is not exceeded.
2
Q
What is elastic deformation?
A
A reversible change in shape due to tensile force where the removal of force will return the object to its original shape.
3
Q
What is plastic deformation?
A
An irreversible change in shape where an object will not return to its original shape.
4
Q
What is the force constant (k)?
A
The amount of force required to produce an extension of one metre.
5
Q
What is extension?
A
The difference in length compared to under load and the original length.
