14 cards from this deck
Extension ∝\propto∝ force if limit of proportionality not exceeded
Point where linear relationship of Hooke's Law ends
Max stretch point where material returns to original shape
Material becomes permanently deformed
F=kxF = kxF=kx
Force applied to spring (N)
Spring constant (N/m)
Extension (m)
Elastic region, follows Hooke's Law
kkk (spring constant)
Plastic behaviour, doesn't follow Hooke's Law
Easy to stretch, lots of extension for little force
Material with only linear graph; snaps instead of stretching after elastic limit
Within limit of proportionality
