WebThe moment of inertia of any shape, including triangle with respect to non-centroidal, and an arbitrary axis can be determined if the moment of inertia of the centroidal axis, which is parallel to the first one, is already known. In this scenario, we use the parallel axes theorem. Web28 aug. 2024 · Start with your hand flat and fingertips pointing along the position vector r pointing from the center of rotation to a point on the force’s line of action. Adjust your hand so the force vector F pushes fingers into a curl. Your thumb then defines the direction of the moment M. Figure 4.1.2. Point-and-curl right-hand rule technique for moments.
