WebThe second moment of area, also known as the area moment of inertia is a cross-section property used in the strengths of materials. The stiffness of a component can be defined by using the moment of inertia I. It is determined by the geometry and size of a cross-section. The symbol for this is I and the unit in SI is mm4, cm4, m4 (that is, L4).
