Resistance to Wooden Structures
Wood is light but has a high resistance. For example, a wood with a specific gravity of 0/6 has a tensile strength of 100 n / m 2, while a steel with a specific gravity of 7/89 has a tensile strength of 500 n / m 2. It is clear that the specific gravity of the steel is more than 13 times greater than the wood, but its tensile strength is only 5 times the wood! If the tensile strength is divided into specific gravity, the number gives us the material quality and the length of the tear. Breaking Length means the point where the material breaks under its own weight. The steel used in the buildings has a length of 4/5 km and an alloy of 17.5 km. When comparing the steel tensile strength with the type of poplar and lime bark, the tensile strengths are 19.8 and 28.3 km, respectively. Now you can better understand why the floors of most sports halls play laminate.
One of the many reasons wood is still used despite its great advances in engineering is durability, weight and safety. The wood can bend slightly, the characteristic of which does not have a brick; so, if the foundation suddenly moves away, the wooden house can be displaced instead of breakage and collapse. Even the smallest change in the foundation of brick houses can cause the cement to leave, which does not look good.
