A preliminary design model to ensure rotational stability for a spacecraft consists of the cylindrical shell and the two square panels as shown. The shell and panels have the same thickness and density. It can be shown that rotational stability about the z-axis can be maintained if I_zz is less than I_xx and I_yy. For a given value of r, determine the limitation for L.
