What is the 3 most important parts of an engineering drawing?

Common features

• Geometry – the shape of the object; represented as views; how the object will look when it is viewed from various angles, such as front, top, side, etc.
• Dimensions – the size of the object is captured in accepted units.
• Tolerances – the allowable variations for each dimension.

What are the 3 types of scale?

There are three types of scales commonly used on maps: written or verbal scale, a graphic scale, or a fractional scale.

What is the unit of RF?

hertz (Hz)

Radio frequency is measured in units called hertz (Hz), which represent the number of cycles per second when a radio wave is transmitted. One hertz equals one cycle per second; radio waves range from thousands (kilohertz) to millions (megahertz) to billions (gigahertz) of cycles per second.

What does DWG stand for?

DWG. AutoCAD Drawing Database (file extension)

What is CAD file format?

CAD (computer-aided design) files are digital files that house 3D & 2D designs as well as information regarding materials, processes, tolerances, and other data. From design to production, everything begins with the CAD file.

What are the 4 types of drawing?

Manual drawing is grouped into four main types: sketches, pictorial, orthographic and full-size set out.

What are the 4 types of technical drawing?

There are many types of technical drawings, including: 3D drawings (isometric, perspective) • Exploded-view 3D drawings • Complete working drawings • Detail drawings (2D orthogonal projections) •Diagrams are another form of technical drawing with looser, less universal standards.

What is ratio level?

The ratio level is the highest of four hierarchical levels of measurement. The levels, or scales, of measurement indicate how precisely data is recorded. The higher the level, the more complex the measurement is. The ratio level contains all of the features of the other 3 levels.

What is the RF scale?

Representative fractions are a unit-less relation between one “unit” on the map and how ever many “units” of the same type on the ground. An RF of 1:24,000 means one inch on the map equals 24,000 inches on the ground and one centimeter on the map equals 24,000 centimeters on the ground.

Is RF AC or DC?

alternating currents
Radio frequency (RF) is a rate of oscillation in the range of around 3 kHz to 300 GHz, which corresponds to the frequency of radio waves, and the alternating currents which carry radio signals.

What is RF formula?

Retention/retardation factor (Rf) can be calculated by the relative migration values of solute (analyte) and the solvent front. Rf = Migration of analyte / Migration of solvent front. The calculation of the Rf value is basically the calculation of relative affinities of a solute with the stationary and mobile phases.
