equipment rack – A rack is a toothed bar or rod which can be thought of as a sector gear with an infinitely large radius of curvature. Torque can be converted to linear pressure by meshing a rack with a pinion: the pinion turns; the rack moves in a straight line. Such a mechanism is utilized in automobiles to convert the rotation of the steering wheel into the left-to-right motion of the tie rod(s). Racks also feature in the theory of gear geometry, where, for instance, the tooth shape of an interchangeable group of gears may be planetary gearbox specified for the rack (infinite radius), and the tooth styles for gears of particular real radii are then derived from that. The rack and pinion gear type is utilized in a rack railway.
