Space Elevator Tether
This interactive simulator explores Space Elevator Tether in Gravity & Orbits. 1D tension vs height; peak near GEO (normalized model). Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: For learners comfortable with heavier math or second-level detail. Typical context: Gravity & Orbits.

How it works
In a rotating frame attached to Earth, a vertical tether feels outward centrifugal force increasing with radius and inward gravity decreasing. Above geostationary altitude centrifugal wins; below, gravity wins. Integrating the net line load gives tension that rises from the surface toward a maximum near GEO, then falls toward a counterweight—this cartoon omits taper, material limits, and lateral loads.
