Spring + elasticity Flashcards
what is the elastic limit of a spring
where it stops going back to its original shape
what is the limit of proportionality
the point the line is no longer straight (graph)
what is meant by inelastic
doesn’t return to its original shape
how do we calculate load on a spring
F = Ke
what is K
hookes law - spring constant (N/m) >to find K on graph do change in y / change in x (F/e)<
what is e
extension in metres
what is it called when spring won’t go back to its original shape
inelastic deformation
what is it called when spring returns to original shape
elastic deformation
when is elastic potential energy stored
when the spring is extended and not inelasticly deformed e.g when its elasticly deformed
how do you calculate elastic P.E
Elastic P.E = 0.5 * K * e^2
what is elastic potential equal to
work done
the higher K the ________ the spring
stiffer
