physics deformation of solids Flashcards
1
Q
youngs modulus
A
stress/strain
the measure of the ability of a material to withstand changes in length with an added load
2
Q
stress
A
F/A
applied force per unit cross sectional area of a material
3
Q
strain
A
e/Lo
extension per unit length
4
Q
elastic deformation
A
an object return to its original form when the force is removed
5
Q
plastic deformation
A
an object does not return to its original form when the force is removed
6
Q
elastic limit
A
the maximum point where the force can be applied to a wire such that the wire will go back to its original form
7
Q
elastic potential energy
A
1/2ke^2
energy stored in an object due to change in shape or size
