TENSEGRITY - How to Build "Impossible" Structures

TL;DR

Learn about tensegrities, structures that challenge our perception of what is possible, and build your own using pure physics.

it's hard to put your finger on it but something about this art is wrong isn't it there's something about the color and the composition and how the shapes fit together that is challenging our brains model of what is normal in what is possible of course we make art like this because it's fun and interesting to be questioned in this way which is why ...

Key Insights

• 🥹 Tensegrities are structures that challenge our perception of what is possible and are held together by a balance of pushing and pulling forces.
• 😒 Engineers use statics to ensure that forces in structures are balanced and to prevent catastrophic failures.
• 💪 Spider silk is an example of tensegrities in nature and is the strongest natural fiber.
• 🛟 Tensegrities may be the unifying architecture of life itself.
• 🍄 Building your own tensegrities structure is an engaging and fun activity that demonstrates the principles of statics and physics.
• 💯 Tensegrities structures can handle external forces without collapsing due to their perfect balance of compression and tension forces.
• 💯 The human spine is also a tensegrities structure, with a perfect balance of pushing and pulling forces.

Questions & Answers

Q: What are tensegrities and how are they different from traditional structures?

Tensegrities are structures that rely on a balance of pushing and pulling forces, with elements under pure compression or pure tension. This creates unique and seemingly impossible designs that are different from traditional structures that rely solely on compression for support.

Q: Why do engineers use statics in their designs?

Engineers use statics to ensure that forces in their structures are balanced and in equilibrium. This prevents unbalanced forces that can lead to catastrophic failures, especially in structures like bridges or houses.

Q: How do tensegrities relate to nature?

Tensegrities can be found in nature, such as in spider silk. Spider silk is composed of elements under tension and compression, making it the strongest natural fiber. This design principle may even be the unifying architecture of life itself.

Q: How can we build our own tensegrities structure?

To build a tensegrities structure, you will need equal length compression pieces (e.g., wood) and tension pieces (e.g., chain or rope). By arranging the pieces in specific configurations and attaching them with hooks or eye bolts, you can create your own impossible, anti-gravity structure.

Summary & Key Takeaways

• Tensegrities are structures that are held together and supported by a careful balance of pushing and pulling forces, creating seemingly impossible designs.

• Engineers use the principles of statics to ensure that forces in structures are balanced and to prevent catastrophic failures.

• Tensegrities can be found in nature, such as in spider silk, and may be the unifying architecture of life.
