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. 9.150 and 9.172: A homogeneous wire with a weight per unit length of 0.041 lb/ft is used to form the figure shown. Determine the moment of inertia of the wire with respect to each of the coordinate axes.
