equipment rack - A rack is a toothed bar or rod that can be regarded as a sector gear with an infinitely large radius of curvature. Torque could be converted to linear drive by meshing a rack with a pinion: the pinion turns; the rack techniques in a straight line. Such a mechanism is used 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 idea of equipment geometry, where, for example, the tooth form of an interchangeable set of gears may be 
specific for the rack (infinite radius), and the tooth shapes for gears of particular actual radii are then derived from that. The rack and pinion gear type is employed in a rack railway.
