Difference (from prior major revision) (minor diff, author diff)

Changed: 1c1

A wing is a surface used to produce lift for a bird or other animal, or a man made device.

A wing is a surface used to produce thrust? by travelling in air or another gaseous? media. The fist use of the word was for the foremost limbs of birds, but has been extended to include or other animal limbs and man made devices.

Added: 2a3

The foremost use of wings are to fly? through downwards thrust (see lift), but wings are also commonly used as a way to produce downforce? and hold objects to the ground (for example [racing car]?s).

Changed: 4c5,11

A helocopter uses a rotating wing with a varible pitch or angle to provide a directional force. The [space shuttle]? uses its wings only for lift during its decent.

Wing construction is complicated and very tightly associated with the science of aerodynamics. Examples of wing use: * A helicopter? uses a rotating wing with a varible pitch or angle to provide a directional force. * The [space shuttle]? uses its wings only for lift during its decent. Constructions of the same purpose as wings, but working in fluid media instead are generally called fins with hydrodynamics as the governing science.
