Deformation Of Solids Flashcards
1
Q
Plastic deformation
A
An object does not go to its original shape and size when force is removed
2
Q
Hooke’s law
A
Provided the limit of proportionality is not exceeded, the extension of an object is proportional to the applied load
3
Q
Stress
A
Strain produced within an object and is force over area
4
Q
Limit of proportionality
A
The point up to which the load is proportional to the extension
5
Q
Strain
A
Ratio of extension over original length
6
Q
Elastic limit
A
Maximum force that can be applied to a wire/spring such that they will return to its original length when force is removed
7
Q
Young modulus
A
Quantity which is obtained by getting the ratio of tensile stress over tensile strain
