can i find the diffrence name of wood?

Question

and the amount

Answer 1

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 either softwood or hardwood. The wood from conifers (e.g. pine) is called softwood, and the wood from broad-leaved 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.

Answer 2

The technology of laminated wood consists in dividing the log into planks, which are then dried and sorted in degrees of quality. They to are then united together to form a ”laminate” about 33 millimetre thick. Finally they are glued together to form beams and structural elements in different sizes. They can be geometric in shape or take on any curved form. Wood laminates improve upon the natural strengths of solid lumber and reduce or eliminate such inherent defects as warping, bowing and shrinkage. Precise lengths can be cut which are consistent in quality throughout the board or the panel, reducing waste and labour in a wide range of applications. Plywood is manufactured by slicing or rotary peeling thin [<2.5 mm] sheets of material [veneer] from a flitch or log and then laminating three or more veneers into a rectangular sheet perhaps 1200 mm × 1200 mm for very thin sheets otherwise 1200 mm × 2400 mm. Laminating an odd number of plies [3, 5, 7 ...] reduces warping while increasing the number of plies increases the resistance to shearing forces.

Answer 3

Yes and no.

You can tell if it is red oak wood, but you can not tell which species of red oak it came from because there are no diffence in the wood itself within the species. This is true also for all white oaks, yellow pines, etc.

Answer 4

Yes, you can find it if you know what you are looking for.
To answer your question you have to be more specific.
I don't know what you are talking about.
