?
What is special about spring constant k?
It has the same value in tension and compression, for a spring.
1 of 9
What is Hooke's law?
Up to a limit of proportionality, force and extension are proportional
2 of 9
How does plastic deformation occur?
Load moves atoms relative to each other; when load is removed, they don't return to their fixed positions
3 of 9
What do ultimate tensile stress and breaking stress depend on?
External conditions, like temperature and pressure.
4 of 9
What does the area under a force-extension graph represent?
Work done to stretch a material
5 of 9
What does the area under a stress-strain graph represent?
Energy per unit volume
6 of 9
What is the yield point?
The point on a stress-strain graph at which the material continues to stretch with no extra load
7 of 9
What is elastic limit?
Point on a stress-strain graph at which material begins to deform plastically
8 of 9
What is limit of proportionality
Point on a stress-strain graph at which a material stops obeying Hooke's law
