Normal Stress Formula
Mechanical stress is the internal force per unit area within a material. For simple axial loading, normal stress is σ = F/A, where F is the applied force and A is the cross-sectional area over which it acts.
This is one of the most fundamental relationships in mechanics of materials, used to check whether a component can safely carry a load by comparing the resulting stress against the material’s allowable or yield stress. Note the result assumes the force is applied uniformly and perpendicular to the cross-section.
