WebFor example, consider the moment created by a push on a door handle. Unless you push with a force exactly perpendicular to the hinge, only a portion of the total moment you produce will act around the hinge axis and be effective to open the door. The moment we are looking for is the vector projection of the moment onto the axis of interest. WebThe inertia of geometric primitives (cylinder, box, sphere) can be computed using Wikipedia's list of moment of inertia tensors (and is used in the above example). The inertia tensor depends on both the mass and the distribution of mass of the object. nelson county va health department
