As one stretches a metal wire,which condition is reached first?
A)the elastic limit
B)the breaking point
C)the proportional limit

Question

Quizplus · Accepted Answer

The proportional limit is the point where Hooke's law is no longer applicable and the relationship between stress and strain becomes non-linear. This point is reached before the elastic limit, where the wire starts to exhibit permanent deformation, and before the breaking point, where the wire fractures.
