WebbStress Strain Curve . Proportional limit is the point on a stress-strain curve at which it begins to deviate from the straight-line relationship between stress and strain. See accompanying figure at (1 & 2). Elastic limit is the maximum stress to which a specimen may be subjected and still return to its original length upon release of the load. WebbThe linearity limit (or the proportionality limit) is the largest stress value beyond which stress is no longer proportional to strain. Beyond the linearity limit, the relation between stress and strain is no longer linear. rock candy suppliersWebbThe proportional limit of steel is 8 10^8N/m^2 and its Young’s modulus is 2 10^11N/m^2 .

Given an independent variable x and a dependent variable y, y is directly proportional to x if there is a non-zero constant k such that The relation is often denoted using the symbols "∝" (not to be confused with the Greek letter alpha) or "~": or Given an independent variable x and a dependent variable y, y is directly proportional to x if there is a non-zero constant k such that The relation is often denoted using the symbols "∝" (not to be confused with the Greek letter alpha) or "~": or WebbThe 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.

WebbHooke’s Law states that the strain of the material is proportional to the applied stress within the elastic limit of that material. Mathematically, Hooke’s law is commonly expressed as: F = –k.x Where F is the force, x is the extension in length, and k is the constant of proportionality known as the spring constant in N/m.
