How to Calculate Space Elevator
What is Space Elevator?
Space elevator is theoretical tether reaching geostationary orbit, lowering launch costs to space by avoiding rockets.
Step-by-Step Guide
- 1Input Earth parameters, cable material properties (strength/density)
- 2Calculate tension distribution along cable
- 3Verify feasibility
Worked Examples
Input
Carbon nanotube cable (theoretical)
Result
Height ~36,000 km, tension manageable with current materials marginally
Material science limitation
Common Mistakes to Avoid
- ✕Neglecting material weight effect
- ✕Ignoring atmospheric drag at lower altitudes
Frequently Asked Questions
Why hasn't anyone built one?
No material simultaneously strong enough and light enough; requires ~100× current material performance.
