Some monoplanes, especially early designs such as the Fokker Eindecker, are also braced to save weight. Braced wings are of two types: Strut braced: one or more stiff struts help to support the wing, as on the Fokker D.VII. A strut may act in compression or tension at different points in the flight regime. Wire braced: alone (as on the Boeing P-26 Peashooter) or, more usually, in addition to struts, tension wires also help to support the wing.
