Normal Stress

This mechanics of materials tutorial introduces the concept of normal stress. It’s essentially the axial force decided by the cross sectional area of a member. For most purposes (including study at this level) it’s sufficient to assume that it the force is spread evenly across the surface. In reality, it’s not completely uniform.
