Wood splitting (riving, [1] cleaving) is an ancient technique used in carpentry to make lumber for making wooden objects, some basket weaving, and to make firewood. Unlike wood sawing , the wood is split along the grain using tools such as a hammer and wedges , splitting maul , cleaving axe , side knife , or froe .
Split-ring resonator is a unit which enhances magnetic permeability and magnetic coupling for metamaterials. Split-ring connector is a ring shaped type of timber connector that is in inserted in routed grooves between timber members in order to reduce stresses to the timbers at the connection points. Commutator (electric), also called split rings.
A typical wood splitting maul has a head mass of 6 to 8 lb or approximately 2.7 to 3.6 kg, respectively. Traditionally, mauls have a wedge-shaped head, but some modern versions have conical heads or swiveling sub-wedges. The original maul resembles an axe but with a broader head. For splitting wood, this tool is much better than a typical axe.
Typical lapped joint assemblies of split-ring connectors. In the 1930s a system of timber framing referred to as the "modern timber connector method" [17] was developed. It was characterized by the use of timber members assembled into trusses and other framing systems and fastened using various types of metal timber connectors.
The annual rings of growth are for many years quite wide, but later they become narrower and narrower. Since each succeeding ring is laid down on the outside of the wood previously formed, it follows that unless a tree materially increases its production of wood from year to year, the rings must necessarily become thinner as the trunk gets wider.

Wood grain is the longitudinal arrangement of wood fibers [1] or the pattern resulting from such an arrangement. [2] R. Bruce Hoadley wrote that grain is a "confusingly versatile term" with numerous different uses, including the direction of the wood cells (e.g., straight grain, spiral grain), surface appearance or figure, growth-ring placement (e.g., vertical grain), plane of the cut (e.g ...
Flat sawn wood (especially oak) will often display a prominent wavy grain (sometimes called a cathedral-window pattern) caused by the saw cutting at a tangent to a growth ring; since in quartersawn wood the saw cuts across the growth rings, the visible grain is much straighter; it is this evenness of the grain that gives quartersawn wood its ...
