A tetrahedron joined by springs is introduced to allow these differentials to distort the shape of a satellite. A dashpot (damper) is used to dissipate energy through tension in the springs as a result of these tidal bulges. We manage to predict the time-scale of tidal locking to within one order of magnitude.

We solve a differential equation in the average distance to the car ahead, and present a graphical argument for stable vs. unstable points in the model. The final state of the program is shown for cases where we have multiple steady-states.
