Behaviour Of Springs & Materials Flashcards
1
Q
Strain
A
The extension per unit length
2
Q
Young Modulus
A
The ratio between stress and strain (Pa) a measure of how difficult it is to change the shape of the material
3
Q
Ultimate Tensile Stress
A
The maximum tensile force that can be applied to an object before it breaks
4
Q
Elastic Deformation
A
The object will return to its original shape when the deforming force is removed
5
Q
Plastic Deformation
A
The object will not return to its original shape when the deforming force is removed, it’s permanently distorted
6
Q
Stress
A
The force per unit cross-sectional area
Pa
