# Shear

From Soft-Matter

To **shear** something is to cause a shear strain, by application of a shear stress. Recall that the shear stress *σ* is given by the applied force *F* over the area *A*, namely

<math>\sigma = \frac{F}{A}</math> ,

and the shear strain *e* is given by

<math>e = \frac{\Delta x}{y}</math> .

See Figure 1 for clarification.
