radius vector — n. pl. radii vectores [vek tôr′ēz] or radius vectors 1. a straight line joining the origin of a vector, located at the intersection of two coordinates, to a given point lying in the same plane 2. a vector whose point of origin is fixed and whose… … English World dictionary
Scrub radius — Scrubradius 0 (top) positive (center) negative(bottom) The scrub radius is the distance in front view between the king pin axis and the center of the contact patch of the wheel, where both would theoretically touch the road. The kingpin axis is… … Wikipedia
Minimum railway curve radius — 90 foot (27.43 m) radii on the elevated 4 ft 8 1⁄2 in (1,435 mm) Chicago L . There is no room for longer radii at this street intersection The minimum railway curve radius, the shortest design radius, has an… … Wikipedia
Plane–sphere intersection — 1. No intersection. 2. Point intersection. 3. Circle intersection.In the theory of analytic geometry for real three dimensional space, the intersection of a plane and a sphere can be the empty set, a point, or a circle.Distinguishing these cases … Wikipedia
Line–sphere intersection — 1. No intersection. 2. Point intersection. 3. Two point intersection.In analytic geometry, a line and a sphere can intersect in three ways: no intersection at all, at exactly one point, or in two points. Methods for distinguishing these cases,… … Wikipedia
Problem of Apollonius — In Euclidean plane geometry, Apollonius problem is to construct circles that are tangent to three given circles in a plane (Figure 1); two circles are tangent if they touch at a single point. Apollonius of Perga (ca. 262 BC ndash; ca. 190 BC)… … Wikipedia

Special cases of Apollonius' problem — In Euclidean geometry, Apollonius problem is to construct all the circles that are tangent to three given circles. Limiting cases of Apollonius problem are those in which at least one of the given circles is a point or line, i.e., is a circle of… … Wikipedia
Glossary of topology — This is a glossary of some terms used in the branch of mathematics known as topology. Although there is no absolute distinction between different areas of topology, the focus here is on general topology. The following definitions are also… … Wikipedia
Johnson circles — In geometry, a set of Johnson circles comprise three circles of equal radius r sharing one common point of intersection H . In such a configuration the circles usually have a total of four intersections (points where at least two of them meet):… … Wikipedia
Tangent lines to circles — In Euclidean plane geometry, tangent lines to circles form the subject of several theorems, and play an important role in many geometrical constructions and proofs. Since the tangent line to a circle at a point P is perpendicular to the radius to … Wikipedia
