Wood!! What do you know about wood???

Where is Wood from??

Wood derives from woody plants, trees. Wood from the latter is only produced in small sizes, reducing the diversity of uses. Wood is a hygroscopicm cellular and anisotropic material.

Uses for the woods!!!

Wood has been used by man long time ago for many purposes, being many things to many people. It used as a material, for making artworks, boats, buildings, furniture, ships, tools, weapons, etc. Wood has been an important construction material since humans began building shelters, and remains in plentiful use today. Construction wood is commonly known as timber an also lumber. Wood may be broken down and be made into chipboard, engineered wood, hardboard, medium-density fibreboard (MDF) , paper or used to make other synthetic substances.

Different Woods

There is a strong relationship between the properties of wood and the properties of the particular tree that yielded it. For every trees species there is a range of density for the wood it yields. There is a rough correlation between density of a wood and its strength (mechanical properties). For example, while mahogany is a medium-dense hardwood which is excellent for fine furniture crafting, balsa is light, making it useful for model building. The densest wood may be black ironwood.

Wood is commonly classified as softwood or hardwood. The wood from conifers (e.g. pine) is called softwood, and the wood from broad-leaced trees (e.g. oak) is called hardwood. These names are a bit misleading, as hardwoods are not necessarily hard, and softwoods are not necessarily soft. The well-known balsa (a hardwood) is actually softer than any commercial softwood. Conversely, some softwoods (e.g. yew) are harder than most hardwoods.
