Moment of inertia of a thin triangular plate bounded by the lines y = x, y = -x, and y = 1 if δ(x, y) = y + 1 kg/m².
20. Center of mass, moments of inertia Repeat Exercise 19 for δ(x, y) = 3x² + 1 kg/m².

21. Moments of inertia Find the moments of inertia of the rectangular solid shown here with respect to its edges by calculating Ix, Iy, and Iz.
22. Moments of inertia The coordinate axes in the figure run through the centroid of a solid wedge parallel to the labeled edges.
