Question

limit of proportionality​

Answer 1

Answer:

The limit of proportionality refers to the point beyond which Hooke's law is no longer true when stretching a material. ... When an elastic object is stretched beyond its limit of proportionality, the object does not return to its original length when the force is removed.

The proportional limit is the point on a stress-strain curve where the linear, elastic deformation region transitions into a non-linear, plastic deformation region. In other words, the proportional limit determines the greatest stress that is directly proportional to strain.
