Inclined Sections

The inclines are the regions of the loop where the rotor rises from the surface to 80km launch altitude.

The forces and masses are per rotor pass. The rotor passes each station twice at altitude, eastbound and westbound, so the forces and masses double. For example, the station mass can be 11452 metric tons. The eastbound rotor passes above the westbound rotor by many hundreds of meters, so the main station support column will be at least that tall.
