Cantilever – The part of a building with no visible means of support.. a cantilever beam – such as a balcony or canopy – projects sometimes worryingly far into thin air without any struts or cables to brace it.  The trick is that the weight of the projecting portion is balanced by downward forces within the main structure of the building.
