Structures: Or Why Things Don’t Fall Down

Description

*Structures: Or Why Things Don’t Fall Down* is a well-known book written by J.E. Gordon, first published in 1978. It’s a classic introduction to the principles of structural engineering, written in a way that makes complex concepts accessible to a general audience. The book explains the basic mechanics and materials used in construction, and it delves into how structures—from bridges to buildings to simple everyday objects—are designed to resist forces like gravity, tension, compression, and shear.

Gordon’s writing is clear, engaging, and often humorous, making complex engineering topics understandable for non-specialists. He emphasizes the importance of understanding the properties of materials and how forces affect them in different ways. His goal is to show how seemingly simple things—like a steel beam or a brick wall—are actually carefully designed and engineered to perform under various conditions.

Key concepts covered in the book include:

1. **Forces and Stresses**: Gordon explains how forces (like weight or pressure) are distributed across structures and the resulting stresses in materials.

2. **Material Properties**: Different materials (wood, steel, concrete, etc.) have distinct characteristics that influence how they respond to forces, and Gordon explains why some materials are more suitable for certain tasks.

3. **Structural Elements**: The book describes how different components of a structure, like beams, columns, and foundations, work together to keep things stable and prevent failure.

4. **Design Considerations**: Gordon introduces the basics of structural design, including factors like safety margins, load-bearing capacity, and redundancy in design (using extra materials or supports to ensure stability).

5. **History and Innovation**: The book also touches on historical developments in engineering and how new materials and techniques have shaped the structures we see today.

6. **Everyday Applications**: Gordon often uses examples from everyday life to illustrate the principles of structural engineering, from the design of a chair to the construction of bridges.

The book is widely regarded as an excellent introduction to structural engineering, and it stands out for its clarity, wit, and ability to simplify the concepts without diluting their importance. It encourages readers to think more deeply about the physical world and the hidden forces that govern the stability of the structures around us.

If you’re interested in understanding why things don’t fall down (or why they do), *Structures* is a fantastic place to start!
