__SPACER__ These structures are more like bones, where the force lines follow the form. If this were the case the structure would be geodesic and ultimately more interesting.<p /><p />To call these monocoque seems to reduce teh term to an absurd conclusion, where a frame structure or truss is called monocoque because its components are hollow. <p /><p />To be this looks like the antithesis of its description as a monocoque structure.
__SPACER__ Almost all forms of plastic tableware could be described as monocoque, showing how meaningless the term is in the context of something like a laptop. I guess if one were to nit pick, the fact that there is no integral roof in a plastic container means that is is not quite the same as a shell structure.
__SPACER__ In the commercial airliner item, I pointed out that many motor cycles which are described as monocoque are stretching the term. However, the classic cafe racer style, with integral seat, does lend itself to something of a monocoque shell for the rider, while relying on a frame chassis to support the engine.
__SPACER__ Semi Monocoque means that there is a frame supporting a shell, where the shell is semi load bearing. This is the ubiquitous form of construction for commercial airliners, but the term is often extended to motorcycles which are clearly frame structures with fairings that have almost no structural role. It is a matter of degree, and therefore open to abuse.
__SPACER__ From this to the more recent Lotus pursuit bikes, the use of complex shaped carbon fiber forms does justify the use of the word monocoque. However, these days many bicycle manufacturers market individual components, such as front forks, as monocoque. A piece of lead pipe could be thus described.
__SPACER__ It is pretty difficult to imagine a shell style helmet that is not monocoque. The sleight of hand here appears to be the fact that all layers are assembled in a single mold, creating an overall single shell. This would perhaps differentiate it from some other designs but not in such as way as they could not also be called monocoque shells.
__SPACER__ Airstream use the word monocoque to refer to the curved glass, not the body. In other words the curve in the glass is in a single piece. Another way of describing this would be to say: "curved glass".<p /><p />The airstream structure looks like the semi monocoque of a commercial airliner, however it may be that a frame takes most of the load.
