A cable beyond geostationary orbit
Follow a climber from the equator past geostationary altitude. Compare inward gravity and outward centrifugal acceleration along the cable.
The model and its limits
Static equatorial cable in a spherical Earth field. The plotted specific-potential difference describes required tension loading, not material feasibility or a complete tapered-cable design.
Equations used in the module
Equations g_eff = Ω²r - GM/r²; r_geo = (GM/Ω²)^(1/3); Φ_eff = -GM/r - Ω²r²/2
