WebThe first moment about the y-axis is the double integral over the region R forming the 2-D plate of the distance from the axis multiplied by the density. M(y) = ∬b aδx dV M(x) = ∬b aδy dV Center of Mass We defined center of mass located in ˉx, ˉy, ˉz. Then it is found from the first moments: ˉx = M(y) M ˉy = M(x) M. Contributors and Attributions

Because r is the distance to the axis of rotation from each piece of mass that makes up the object, the moment of inertia for any object depends on the chosen axis.
WebMoments are experimental characteristics of the outlet flux that can readily be obtained in closed form from their Laplace transforms.
