WebMoments of Inertia. For a clear understanding of how to calculate moments of inertia using double integrals, we need to go back to the general definition in Section \(6.6\). The moment of inertia of a particle of mass \(m\) about an axis is \(mr^2\) where \(r\) is the distance of the particle from the axis. WebThe lecture includes definitions for the area, Cg of an area, and the first moment of area, Moment of inertia, and product of inertia. Skip to content. Engineering Oasis Home; ...
