A material's property or material property is an intensive property of some material, i.e. a physical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.. A property may be a constant or may be a function of one or more
Moisture properties of wood. Wood is a hygroscopic, meaning it is a material that absorbs water. Water gets into wood in three ways: as a fluid through the cell lumens through capillary tension, as vapour through the cell lumens, and as molecular diffusion through the cell walls. The moisture content of wood means the relationship between the
Mechanical Properties of Wood David E. Kretschmann, Research General Engineer 5 1 materials. Because wood is a natural material and the tree is subject to many constantly changing influences such as moisture, soil conditions, and growing space , wood proper-
Wood is a very light material, its specific gravity being always less than 1 that of water . It is interesting to note, however, that if the wood tissue is compacted in such a way that not even a few pores are left in it, then its specific gravity will approach 1.5 i.e., it will become heavier than water .

Wood has been used as a building material for thousands of years, being second only to stone in terms of its rich and storied history in the world of construction. The chemical properties of wood are inherently complex, but even in spite of this challenge, human beings have successfully harnessed the unique characteristics of wood to build a seemingly unlimited variety of structures.
The mechanical properties of wood, including specific gracity, strength, bending strength, movement, stability, working characteristics, and common uses. Part of the Workshop Companion, a collection of information on wood, woodwork, woodworking skills, woodworking materials, and woodworking plans that together form the core knowledge needed by woodworkers, furniture makers, cabinetmakers
complex material with many properties. One definition of wood is that it is a hygroscopic, anisotropic material of biological origin. do various mechanical properties of wood. So, wood is anisotropic in both its hygroscopic behavior as well as its mechanical behavior. SWST Teaching Unit 2 Slide Set 1. and > >
THE PROPERTIES OF MATERIALS and their everyday uses Children need to have experience of, and explore as many different materials: wood, metals copper, tin, steel, gold, silver, aluminium, chrome, materials have properties that are appropriate for specific uses and by
