Example 6.6.8



 Find the moments of inertial ${I}_{x}$ and ${I}_{y}$, the total mass $m$, and the radii of gyration ${R}_{x}$ and ${R}_{y}$ of the lamina that has the shape of an isosceles right triangle with legs of length 1, and has density that is twice the square of the distance from the vertex of the right angle. Hint: Put the right angle at the origin. See Example 6.5.8.
