Up to a certain limit only, the stress is directly proportional to strain. Hooke’s law is valid only in this linear part of the stress-strain curve. The slope of the linear curve gives Young’s modulus of the material.

WebStrain is a measurement of how an object reacts to stress. Strain is simply a measurement of what the percentage change in an object's shape is when a certain stress is applied to it. A good way to demonstrate strain is with a rubber band. Suppose we have a rubber band that is 100 inches long. WebIn engineeringand materials science, a stress–strain curvefor a material gives the relationship between stressand strain. It is obtained by gradually applying loadto a test coupon and measuring the deformation, from which the stress and strain can be determined (see tensile testing). piano graphic hand drawn
