Normal stress can be caused by several loading methods, the most common being axial tension and compression, bending, and hoop stress." . "\\(\\sigma = \\frac{dF_n}{dA}\\), where \\(dF_n\\) is the normal component of force and \\(dA\\) is the area of the surface element."^^ . . . . . . "\\(\\sigma\\)"^^ . . . . . . . .
