Define strain a level physics

WebStress is a measure of the force put on the object over the area. Strain is the change in length divided by the original length of the object. Experiments have shown that the change in length (ΔL) depends on only a few variables. As already noted, ΔL is proportional to the force F and depends on the substance from which the object is made. WebTensile force per unit area of cross-section is called tensile stress, σ. Extension per unit length of the material is called tensile strain, ε. Elastic …

Σ =F/A. where, σ is stress applied. F is force applied. A is the area of force applied. Stress is measured by unit N/m2. WebShear strains. A shear strain results from shear stress and it is a strain computed from relative displacements that are measured parallel to two reference planes. Shear strains measure the relative parallel movement of one reference plane with respect to another.
