Chapter 6 Materials Flashcards
1
Q
Compressive vs Tensile Forces
A
- Compressive forces produce compression
- Tensile forces produce extension
2
Q
What is Hooke’s Law?
A
The extension of a spring is directly proportional to the force applied
3
Q
Elastic vs Plastic Deformation
A
- Elastic Deformation means the spring will return to its original length
- Plastic Deformation is a permanent structural change
- Plastic Deformation happens after the elastic limit
4
Q
What does k measure?
A
The stiffness of the spring
5
Q
Area under a force-extension graph:
A
Work Done (W = Fx)
6
Q
Formula for EPE:
A
E = 1/2(kx^2)
