horseshoe β a U -shaped metal plate, plain or with calks, nailed to a horse's hoof to protect it from being injured by hard or rough surfaces.
hyperbola β the set of points in a plane whose distances to two fixed points in the plane have a constant difference; a curve consisting of two distinct and similar branches, formed by the intersection of a plane with a right circular cone when the plane makes a greater angle with the base than does the generator of the cone. Equation: x 2 /a 2 β y 2 /b 2 = Β±1.
meniscus β a crescent or a crescent-shaped body.
ogee β a double curve, resembling the letter S, formed by the union of a concave and a convex line.
parabola β a plane curve formed by the intersection of a right circular cone with a plane parallel to a generator of the cone; the set of points in a plane that are equidistant from a fixed line and a fixed point in the same plane or in a parallel plane. Equation: y 2 = 2 px or x 2 = 2 py.
quirk β a peculiarity of action, behavior, or personality; mannerism: He is full of strange quirks.
sinuosity β Often, sinuosities. a curve, bend, or turn: a sinuosity of the road.
sweep β to move or remove (dust, dirt, etc.) with or as if with a broom, brush, or the like.
swerve β to turn aside abruptly in movement or direction; deviate suddenly from the straight or direct course.
sphere β Geometry. a solid geometric figure generated by the revolution of a semicircle about its diameter; a round body whose surface is at all points equidistant from the center. Equation: x 2 + y 2 + z 2 = r 2 . the surface of such a figure; a spherical surface.
wheel β a circular frame or disk arranged to revolve on an axis, as on or in vehicles or machinery.
