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

Question

Quizplus · Accepted Answer

The proportional limit is the first condition reached when stretching a metal rod. It is the point up to which the stress and strain in the material are directly proportional, meaning the material will return to its original shape when the stress is removed. Beyond this point, the material will not behave elastically, leading to permanent deformation.
