1
Q
what is the limit of proportionality?
A
beyond this point force is no longer proportional to extension
2
Q
what is the elastic limit?
A
if force is increased past the elastic limit the object will be permanently stretched (plastic deformation)
3
Q
what is elastic strain energy?
A
the energy stored by a material that is being stretched
4
Q
what is the UTS?
A
the ultimate tensile stress is the maximum stress a material can withstand
