Why is understanding equilibrium moisture content important for carpenters?

To ensure the wood remains lightweight

To prevent wood warping or cracking during use

Understanding equilibrium moisture content (EMC) is crucial for carpenters because it directly influences the stability and durability of wooden materials. Woods naturally absorb and release moisture, which can lead to changes in size and shape. When the moisture content of wood reaches equilibrium with the surrounding environment, it helps to maintain stability. If wood is not at its EMC during processing or installation, it may expand or contract as it acclimates, leading to warping, cracking, or other forms of damage once it is subjected to varying humidity levels. This knowledge enables carpenters to select, store, and use wood more effectively, ultimately ensuring the quality and longevity of their projects.
