It will be tricky adding tidal stress to the rotovator's stress from centrifugal force, but I think I can tweak Wolfe's spreadsheet to do the job.MoonLunar elevator going from Mösting Crater through a balance point at EML1Lunar vertical tether from an anchor mass at 30,000 km altitudeMarsPhobos anchored vertical tether.Deimos anchored vertical tether.CeresClarke style elevators from Ceres.
