In statistics, an ogive, also known as a cumulative frequency polygon, can refer to one of two things: any empirical cumulative distribution function. The points plotted as part of an ogive are the upper class limit and the corresponding cumulative absolute frequency [2] or cumulative relative frequency. The ogive for the normal distribution ...
The ogive radius ρ is not determined by R and L (as it is for a tangent ogive), but rather is one of the factors to be chosen to define the nose shape. If the chosen ogive radius of a secant ogive is greater than the ogive radius of a tangent ogive with the same R and L, then the resulting secant ogive appears as a tangent ogive with a portion ...
A secant ogive of sharpness. The ogive shape of the Space Shuttle external tank. Ogive on a 9×19mm Parabellum cartridge. An ogive (/ ˈoʊdʒaɪv / OH-jyve) is the roundly tapered end of a two- or three-dimensional object. Ogive curves and surfaces are used in engineering, architecture, woodworking, and ballistics.
The resulting fixed drag curve models for several standard projectile shapes or types are referred to as the: G7 shape standard projectile. All measurements in calibers/diameters. G1 or Ingalls (flatbase with 2 caliber (blunt) nose ogive - by far the most popular) G2 (Aberdeen J projectile) G5 (short 7.5° boat-tail, 6.19 calibers long tangent ...
Ballistic coefficient. A selection of bullets with different shapes, and hence, different ballistic coefficients. In ballistics, the ballistic coefficient (BC, Cb) of a body is a measure of its ability to overcome air resistance in flight. [1] It is inversely proportional to the negative acceleration: a high number indicates a low negative ...
The following is a list of centroids of various two-dimensional and three-dimensional objects. The centroid of an object in -dimensional space is the intersection of all hyperplanes that divide into two parts of equal moment about the hyperplane.
t. e. A normal distribution or Gaussian distribution (also known as the "bell-shaped curve") is a concept used in probability theory and statistics. [ 2 ] The normal distribution concept is applied in numerous disciplines, including education, psychology, economics, business, the sciences and nursing.
Ogee. An ogee (/ oʊˈdʒiː / / ˈoʊdʒiː /) is an object, element, or curve —often seen in architecture and building trades—that has a serpentine- or extended S-shape (sigmoid). [1]: 218 Ogees consist of a "double curve", the combination of two semicircular curves or arcs that, as a result of a point of inflection from concave to convex ...
