WebAug 1, 2024 · This adjustment process with the equations above is the parallel axis theorem. The area or mass terms simply represent the area or mass of the part you are looking at, while the distance ( r) represents the distance that we are moving the axis about which we are taking the moment of inertia. WebSep 20, 2024 · The parallel axis theorem for products of inertia is (10.7.2) I x y = I ¯ x ′ y ′ + A x ¯ y ¯. Unlike the rectangular moments of inertia, which are always positive, the product of inertia may be either positive, negative, or zero, depending on the object's shape and the orientation of the coordinate axes.
