For the component described in the problem indicated, determine (a) the principal mass moments of inertia at the origin, (b) the principal axes of inertia at the origin. Sketch the body and show the orientation of the principal axes of inertia relative to the x, y, and z axes.
Probs. 9.145 and 9.149 Determine the mass moment of inertia of the steel fixture shownwith respect to (a) the x axis, (b) the y axis, (c) the z axis. (Thedensity of steel is 7850 kg/m3.)
