American Wire Gauge ( AWG) is a logarithmic stepped standardized wire gauge system used since 1857, predominantly in North America, for the diameters of round, solid, nonferrous, electrically conducting wire. Dimensions of the wires are given in ASTM standard B 258. [ 1] The cross-sectional area of each gauge is an important factor for ...
A compass, also commonly known as a pair of compasses, is a technical drawing instrument that can be used for inscribing circles or arcs. As dividers, it can also be used as a tool to mark out distances, in particular, on maps. Compasses can be used for mathematics, drafting, navigation and other purposes. Prior to computerization, compasses ...
In mathematics, Euler's identity[ note 1] (also known as Euler's equation) is the equality where. is pi, the ratio of the circumference of a circle to its diameter. Euler's identity is named after the Swiss mathematician Leonhard Euler. It is a special case of Euler's formula when evaluated for .
Craftsbury Academy, located on Craftsbury Common is among the oldest and smallest public high schools in Vermont, and is part of the town's K–12 school system. Sterling College is nearby on Craftsbury Common and is a college of ecological thinking and action and is recognized as a Work College by the U.S. Department of Education.
The turning radius (alternatively, turning diameter or turning circle) of a vehicle defines the minimum dimension (typically the radius or diameter, respectively) of available space required for that vehicle to make a semi-circular U-turn without skidding. The Oxford English Dictionary describes turning circle as "the smallest circle within ...
A circular mil is a unit of area, equal to the area of a circle with a diameter of one mil (one thousandth of an inch or 0.0254 mm). It corresponds to approximately 5.067 × 10−4 mm2. It is a unit intended for referring to the area of a wire with a circular cross section. As the definition of the unit contains π, it is easy to calculate area ...
Geometry template. Stencil for the curves of y = x2, y =tan ( x ), y =sin ( x ), and y = 1 2 sin ( x ). A geometry template is a piece of clear plastic with cut-out shapes for use in mathematics and other subjects in primary school through secondary school. It also has various measurements on its sides to be used like a ruler.
In 1992, the American National Standards Institute adopted ANSI/ ASME Y14.1 Decimal Inch Drawing Sheet Size and Format, [ 1] which defined a regular series of paper sizes based upon the de facto standard in × 11 in "letter" size to which it assigned the designation "ANSI A". This series also includes "ledger"/"tabloid" as "ANSI B".
