Tensegrity Principles
Tensegrity (tensional integrity) is a structural principle where compression elements (struts) are isolated and held in place by a continuous network of tension elements (cables). The Dymaxion House exemplifies this principle with its central mast and radiating tension cables.

陽Compression (Yang)
- • Discontinuous: Isolated struts do not touch
- • Particle-like: Discrete compression elements
- • Convex: Outward-pushing forces
- • Islands: Compression members "float" in tension sea
- • Example: Central aluminum mast (Dymaxion House)
陰Tension (Yin)
- • Continuous: Unbroken network throughout
- • Wave-like: Distributed tension field
- • Concave: Inward-pulling forces
- • Sea: Continuous medium holding compression
- • Example: 16 radiating cables (Dymaxion House)
Structural Benefits
Maximum Efficiency
Minimum material for maximum strength - cables only resist tension, struts only resist compression
Self-Stabilizing
Pre-stressed system maintains equilibrium without external support
Lightweight Design
Dymaxion House: 2,700kg total weight for 11m diameter structure

Force Equilibrium
Σ Ftension + Σ Fcompression = 0
For the Dymaxion House:
• Central mast: Vertical compression = -Fc
• 16 cables: Radial tension = 16 × Ft
• Equilibrium: Fc = 16 × Ft × sin(θ)
