Technical standards exist to provide glossaries of abbreviations, acronyms, and symbols that may be found on engineering drawings. Many corporations have such standards, which define some terms and symbols specific to them; on the national and international level, ASME standard Y14.38 [1] is one of the standards. Australia utilises the ...
A minimum off-route altitude (MORA) provides a quick way for an aircraft pilot to read the minimum altitude required for terrain and obstacle clearance. MORAs give at least 1,000 feet altitude clearance above terrain and obstacles such as radio masts, and 2,000 feet where the terrain and obstacles exceed 5,000 feet. [1]
An engineering drawing is a type of technical drawing that is used to convey information about an object. A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing.
Example of true position geometric control defined by basic dimensions and datum features. Geometric dimensioning and tolerancing (GD&T) is a system for defining and communicating engineering tolerances via a symbolic language on engineering drawings and computer-generated 3D models that describes a physical object's nominal geometry and the permissible variation thereof.
Engineering can be a very broad term. It stems from the Latin ingenerare, meaning "to create". [6] Because this could apply to everything that humans create, it is given a narrower definition in the context of technical drawing. Engineering drawings generally deal with mechanical engineered items, such as manufactured parts and equipment.
A less common symbol is simply a series of peaks on one side of the line representing the conductor, rather than back-and-forth. Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle ...
Electrical engineering uses "j" to represent the imaginary unit "i", to prevent confusion with the symbol for current. =. Jedlik's dynamo An early form of electric generator using electromagnets. JFET A field effect transistor with a reverse-biased PN junction between gate and channel. jitter
In engineering, a symbolic language is a language that uses standard symbols, marks, and abbreviations to represent concepts such as entities, aspects, attributes, and relationships. [1] [original research?] Engineering symbolic language may be used for the specification, design, implementation, management, operation, and execution of ...
