Cable Yarding System in Lushoto, Tanzania. Skyline logging (or skyline yarding) is a form of cable logging in which harvested logs are transported on a suspended steel cable (a cableway or "highline") from where the trees are felled to a central processing location.
High Lead logging in Western Oregon Cable grue Larix 3T, installed on agricultural tractor. Cable logging, also referred to as skyline logging, is a logging method primarily used on the West Coast of North America with yarder, loaders, and grapple yarders, but also in Europe (Austria, Switzerland, Czech Republic, France, Italy).
Billet is variously defined as a short piece of round or partially round wood (usually a smaller diameter than a block or bolt [7]) or as a piece split or cut from a bolt, or sometimes synonymous with bolt, particularly when the pieces are intended as firewood, and sometimes means a piece of a billet after it has been split.
[1] [2] It is named after R. H. Wood. According to this method, the ratio between the critical buckling length and the real length of a column is determined based on two redistribution coefficients, η 1 {\displaystyle \eta _{1}} and η 2 {\displaystyle \eta _{2}} , which are mapped to a ratio between the effective buckling length of a ...
Distance sampling is a widely used group of closely related methods for estimating the density and/or abundance of populations. The main methods are based on line transects or point transects .
A cable in this usage cable is a thick rope or by transference a chain cable. [1] The OED gives quotations from c. 1400 onwards. A cable's length (often "cable length" or just "cable") is simply the standard length in which cables came, which by 1555 had settled to around 100 fathoms (600 ft; 180 m) or 1 ⁄ 10 nautical mile (0.19 km; 0.12 mi).

Hankinson's equation (also called Hankinson's formula or Hankinson's criterion) [1] is a mathematical relationship for predicting the off-axis uniaxial compressive strength of wood. The formula can also be used to compute the fiber stress or the stress wave velocity at the elastic limit as a function of grain angle in wood .
