for the motion of a system in a resisting medium; the SPS moves on a geocentric orbit in the form of a circle in a vertical plane and there is a resistance such as frictional force caused by structural flexibility and/or drag force, to motion proportional to the rotational angle rate 3. In the presence of such a dissipation term, Eq. 5 is replaced by where the positive multiplier, a, is small. To have a damped oscillatory solution, it requires for some integer n. Since is monotonic and bounded on the open interval 0 < t <°°, where C is a positive constant. Now assume that lim(0) exists and equals C. Application of the limiting comparison test for infinite integrals yields C = 0; otherwise
