Mechanical stress \( \sigma \) refers to the force acting on a given surface of an object. In this illustration, a force \( \class{red}{F} \) (here: tensile force) acts on the side face \( A \) of a cube. The mechanical stress indicates how much pressure or, as in this case, tension is exerted on a surface of the cube.
