Wood

=Wood =




 * ===Wood is an organic material; in the strict sense it is produced as secondary xylem in the stems of trees (and other woody plants). ===


 * ===Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or wood chips or fiber. ===


 * ===Wood forms around a central core in a series of concentric layers called growth rings. ===

The most widely used woods come from two groups of trees:

 * ===The conifers or softwoods (e.g., pine, spruce, fir) ===


 * ===The hardwoods (e.g., oak, walnut, maple) ===

Properties

 * ===Density and moisture content affect the strength of wood; in addition to load strength, other variable factors often tested include elasticity and toughness. ===


 * ===Wood is insulating to heat and electricity and has desirable acoustical properties. ===


 * ===Some identifying physical characteristics of wood include colour, odour, texture, and grain (the direction of the wood fibres). ===
