  2. Sagitta (geometry) - Wikipedia

    en.wikipedia.org/wiki/Sagitta_(geometry)

    In the following equations, denotes the sagitta (the depth or height of the arc), equals the radius of the circle, and the length of the chord spanning the base of the arc. As 1 2 l {\displaystyle {\tfrac {1}{2}}l} and r − s {\displaystyle r-s} are two sides of a right triangle with r {\displaystyle r} as the hypotenuse , the Pythagorean ...

  3. Structure gauge - Wikipedia

    en.wikipedia.org/wiki/Structure_gauge

    The code also defines the clearance that is shorter than the physical clearance to account for sag curves, bridge deflection and expected settlements with a recommendation of minimum clearance of 5 metres (16 ft 5 in). [2] In UK, the "standard minimum clearance" for structures over public highways is 16 feet 6 inches (5.03 m). [3]

    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. One corporation can have many CAGE codes, as can one government, because each division, department, and site (campus) can have its own CAGE code.

  5. Bitting (key) - Wikipedia

    en.wikipedia.org/wiki/Bitting_(Key)

    Bitting is the depth of key cuts on a cylinder key for a pin tumbler lock, often expressed as a number. Bitting also refers to the combination of key cuts on a bit key for a warded lock or lever tumbler lock. The exact geometry of modern keys is usually described by a code system. [1]

  6. Aspect ratio - Wikipedia

    en.wikipedia.org/wiki/Aspect_ratio

    For example, the aspect ratio of a rectangle is the ratio of its longer side to its shorter side—the ratio of width to height, [1] [2] when the rectangle is oriented as a "landscape". The aspect ratio is most often expressed as two integer numbers separated by a colon (x:y), less commonly as a simple or decimal fraction. The values x and y do ...

  7. Slenderness ratio - Wikipedia

    en.wikipedia.org/wiki/Slenderness_ratio

    Structural engineers generally consider a skyscraper as slender if the height:width ratio exceeds 10:1 or 12:1. Slim towers require the adoption of specific measures to counter the high strengths of wind in the vertical cantilever , like including additional structures to endow greater rigidity to the building or diverse types of tuned mass ...

  9. Length - Wikipedia

    en.wikipedia.org/wiki/Length

    Various terms for the length of a fixed object are used, and these include height, which is vertical length or vertical extent, width, breadth, and depth. Height is used when there is a base from which vertical measurements can be taken. Width and breadth usually refer to a shorter dimension than length. Depth is used for the measure of a third ...
