In green, the point with radial coordinate 3 and angular coordinate 60 degrees or (3,60°). In blue, the point (4,210°). By measuring bearings and distances, local polar coordinates are recorded. The orientation of this local polar coordinate system is defined by the 0° horizontal circle of the total station (polar
A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board.The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15.
CAD: computer-aided design, computer-aided drafting; cadmium [plating]: CAGE: Commercial and Government Entity [code]: A CAGE code is a unique identifier to label an entity (that is, a specific government agency or corporation at a specific site) that is a CDA, ODA, or MFR of the part defined by the drawing.
Lofting coordinates are used for aircraft body measurements. The system derives from the one that was used in the shipbuilding lofting process, with longitudinal axis labeled as "stations" (usually fuselage stations , frame stations , FS ), transverse axis as "buttocks lines" (or butt lines , BL ), and vertical axis as " waterlines " (WL).
A standard Brunton compass, used commonly by geologists and surveyors to obtain a bearing in the field. In navigation, bearing or azimuth is the horizontal angle between the direction of an object and north or another object. The angle value can be specified in various angular units, such as degrees, mils, or grad. More specifically:
The bearing surface describes the contact area between two objects used as datum. It is often the underside of a screw head (male seat, marked A) or a flat at the end of the screw thread (female seat, marked B). A bearing surface in mechanical engineering is the area of contact between two objects.
Diagram of an open traverse. Open traverse: neither returns to its starting station, nor closes on any other known station. Diagram of a closed traverse; Compound traverse: it is where an open traverse is linked at its ends to an existing traverse to form a closed traverse. The closing line may be defined by coordinates at the end points which ...
A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.
