Tree taper is the degree to which a tree's stem or bole decreases in diameter as a function of height above ground. Within Forestry and for the purposes of timber production, trees with a high degree of taper are said to have poor form, while those with low taper have good form. The opposite is the case for open-grown amenity trees.
A rod with a fast taper will only flex the top 20 percent. Medium fast and medium tapers will flex approximately 30 to 60 percent of the rod respectively. If the rod has a slow taper, almost the entire rod or blank will bend or flex under pressure.
Girard form class is a form quotient calculated as the ratio of diameter inside bark at the top of the first 16 foot log to the diameter outside bark at breast height ().Its purpose is to estimate board-foot volume of whole trees from measurement of DBH, estimation of the number of logs, and estimation of the taper of the first log, based on the general relationships identified between the ...
In engineering, draft is the amount of taper for molded or cast parts perpendicular to the parting line. It can be measured in degrees or mm/mm (in/in). Consider the fabrication of a hollow plastic box, without lid. Once the plastic has hardened around the mold, the mold must be removed. As the plastic hardens, it may contract slightly.
The volumes of 34 trees fall within the hypothetical upper and lower-bound calculations. [31] Better results can be obtained using subjectively assigned factors to incorporate the taper of the trunk and characterize the basal flare. Trees with major root flare or pronounced taper skew the formula.
The capstan equation [1] or belt friction equation, also known as Euler–Eytelwein formula [2] (after Leonhard Euler and Johann Albert Eytelwein), [3] relates the hold-force to the load-force if a flexible line is wound around a cylinder (a bollard, a winch or a capstan).
A taper pin is a fastener used in mechanical engineering. They are steel rods with one end having a slightly larger diameter than the other. Metric taper pins have a taper of 1:50. [1] A 1:50 taper means that one end of a 50 mm long bar will be 1 mm smaller in diameter than the other end.
Fishing rod taper, a measure of the flexibility of a fishing rod; Conically tapered joints, made of ground glass, commonly used in chemistry labs to mate two glassware components fitted with glass tubings; Luer taper, a standardized fitting system used for making leak-free connections between slightly conical syringe tips and needles
