7 hasses are attached by a lightweight rod This object orbits a planet the length of the rod is smaller than the radius of the orbit but not negligible The rod rotates about its axis in such a way that it remains vertical with respect to the planet Assume in each case perturbation maintains the rate of rotation so that in the co rotating frame the rod is still stationary but at an angle to the vertical 1 There is no force in the rod the equilibrium is neutral with respect to a small perturbation in the angle of the rod 2 The rod is in tension the equilibrium is stable with respect to a small perturbation in the angle of the rod 3 The rod is in compression the equilibrium is stable with respect to a small perturbation in the angle of the rod 4 The rod is in tension the equilibrium is unstable with respect to a small turbation in the angle of the rod
