Normal stress is when a force is or a distribution of forces are acting perpendicular to the surface per unit area. The general equation for normal stress is:
(Eq1)
σ =
P
A
The equation states that stress equals force per unit area. The intensity of the forces distributed over a given section is called the stress on that section. Normal stress is associated with axial loading.
