Unit 1- Materials Flashcards
1
Q
Ultimate tensile strength / breaking stress
A
Maximum stress a material can withstand without fracturing
2
Q
Plastic deformation / beyond elastic limit
A
When a material does not return to its original shape when the force is removed
3
Q
Elastic deformation
A
When a material returns to its original shape when the force is removed
4
Q
Strain
A
Extension / original length
5
Q
Stress
A
Force applied / cross-sectional area
6
Q
Young modulus
A
Stress / strain
7
Q
Force constant
A
Force per unit extension
8
Q
Hooke’s Law
A
Extension is proportional to applied force (provided elastic limit is not exceeded)
