Wood

=Wood =



===Wood is an organic material, a natural composite of cellulose fibers (which are strong in tension) embedded in a matrix of lignin which resists compression. In the strict sense wood is produced as secondary xylem in the stems of trees (and other woody plants). ===

===People have used wood for millennia for many purposes, primarily as a fuel or as a construction material for making houses, tools, weapons, furniture, packaging, artworks, and paper. ===

===<span style="font-family: 'Comic Sans MS',cursive;">Wood has been an important construction material since humans began building shelters, houses and boats. Nearly all boats were made out of wood until the late 19th century, and wood remains in common use today in boat construction. === ===<span style="font-family: 'Comic Sans MS',cursive;">Wood to be used for construction work is commonly known as lumber in North America. Elsewhere, lumber usually refers to felled trees, and the word for sawn planks ready for use is timber. === ===<span style="font-family: 'Comic Sans MS',cursive;">New domestic housing in many parts of the world today is commonly made from timber-framed construction. Engineered wood products are becoming a bigger part of the construction industry. They may be used in both residential and commercial buildings as structural and aesthetic materials. === ===<span style="font-family: 'Comic Sans MS',cursive;">In buildings made of other materials, wood will still be found as a supporting material, especially in roof construction, in interior doors and their frames, and as exterior cladding. ===

<span style="font-family: 'Comic Sans MS',cursive;">Wood is also commonly used as shuttering material to form the mould into which concrete is poured during reinforced concrete construction.
