PROBLEM 9.159 Brass wire with a weight per unit length wis used to form the figure shown. Determine the products of inertia ,xyI,yzIand zxIof the wire figure. SOLUTION First compute the mass of each component. Have 1WmwLgg==Then.. 13322wwmaaggππ=×=()2agg3agg=Now observe that the centroidal products of inertia, ,,xyyzII′′′′and ,zxI′ ′of each component are zero because
