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

Question

Quizplus · Accepted Answer

The proportional limit is reached first when stretching a metal wire. This is the point up to which the stress and strain are directly proportional to each other, following Hooke's Law. Beyond this limit, the material no longer returns to its original shape or size once the force is removed, indicating the beginning of permanent deformation.
