4.1 Deformation Of Solids Flashcards
1
Q
Hooke’s Law
A
Up to a maximum load, known as the limit of proportionality, the extension of an elastic material is proportional to the applied load
2
Q
Define the limit of proportionality
A
The point beyond which Hooke’s law is no longer true
3
Q
Define the Elastic Limit
A
The maximum load a specimen can experience and still return to its original length when the deforming force is removed
4
Q
Up to the elastic limit the material is undergoing
A
Elastic deformation
5
Q
Define stress
A
The applied force per unit area of cross section
6
Q
Define strain
A
The ration of the change in length if a specimen to its original length
7
Q
Define Young Modulus
A
Within the limit of proportionality, the ratio of stress to strain
