Although an ex-tensive review that compares all properties of wood-based materials and products is beyond the scope of this chapter, Table 12–1 provides some insight to how static bending properties of these materials vary and how their properties Lumber Sizing Chart. It is strong in relation to its weight, is insulating to heat and electricity, and has desirable acoustic properties. Properties of Birch and Maple wood. The chart of “Mechanical Properties of Wood” is divided into three parts -- North American Hardwoods, North American Softwoods, and World Woods, or woods from other places than North America. Chapter 7 "Timber and cellulose" is a great introduction to how wood's properties are determined by the inner stucture of trees and their growth. The natural colour of the wood is a pale golden brown, but it can be bleached or stained to simulate other woods, e.g. The table below provides laboratory values for several properties of wood that are associated with wood strength. Wood, the principal strengthening and nutrient-conducting tissue of trees and other plants and one of the most abundant and versatile natural materials. Because wood is a natural material and the tree is subject … Factors Affecting Wood Properties 2.1 Natural Characteristics Related to Wood Structure Much of the variation in wood properties within and between trees can be attributed to density. In tension (for example, stretched horizontally in struts or beams), it's one of the weakest of all common materials. Easy board foot calculation Hardwoods sell in grades by the board foot, a basic unit of measurement that equals a 1"-thick board that's 12" wide and 12" long.That's because hardwoods--unlike softwoods-aren't cut and milled as dressed, sized lumber in standard nominal dimensions (2X4, 1X6, 4X4, etc.) Botanical name: Acer saccharum Color: Color ranges from cream to light reddish brown. Variability, or variation in properties, is common to all materials. The cell wall substance is actually heavier than water; with a specific gravity of about 1.5 kgm–3 regardless of species. Appearance: The pattern is usually straight-grained and sometimes found with highly figured bird's-eye or burl grain. Physical features: Maple wood properties also include that this wood type is heavy, hard, strong, tough, stiff, close-grained, and possesses a uniform texture. It is a relatively cheap wood and the durability of this wood makes it a good choice for doors, floors, structural parts of furniture, plywood and veneers. ... Penguin, 1991. Chart: Wood can be very weak. walnut and mahogany. Learn more about wood in this article. To access any part, click on the title below. to only be cut to length for construction. For younger readers. properties to represent the average properties of a species is uncertain; nevertheless, the properties represent the best information available.
