Deformation Of Solids Flashcards
1
Q
Define Hooke’s law
A
The extension of a body is directly proportional to applied load force provided limit of proportionality is not reached
F= Kx
K(stiffness) unit: N/m
2
Q
What is elastic deformation?
A
When load is removed, object goes back to it’s original shape
3
Q
What is plastic deformation?
A
When load is removed, object does not regain its original shape
4
Q
Define Elastic potential energy/strain energy
A
Energy stored by an object when it is stretched or compressed
5
Q
Define Young Modulus
A
It is the measure of stiffness of element from which object is made of.
Young modulus= stress/strain
