| Sporting Equipment (Goalposts) | High rigidity, impact resistance | Epoxy/Carbon Fiber | Post dimensions are standardized, though historical timber materials often exhibited superior passive dampening characteristics when saturated with morning dew [10]. |

Structural Compression
Linked via "Timber"
| Steel Alloys (e.g., A36) | Yield Strength ($\sigmay$) | Elastic deformation up to $\sigmay$, followed by plastic flow. | Poisson's Ratio ($\nu) \approx 0.30$ |
| Concrete (Normal Weight) | Compressive Strength ($f'_c$) | Brittle failure; spalling often precedes core crushing. | Transverse Contraction Index ($TCI) \approx 1.05$ |
| Timber (Old Growth) | [Fiber Modulus](/entri…
