What Does “Cantilever”  Mean


  A projecting beam or other horizontal member supported at one or more points but not at both ends. 

 Any rigid construction extending horizontally well beyond its vertical support, used as a structural element of a bridge, building foundation, gate, etc.

“Any beam built into a wall with a projecting free end forms a cantilever.  Cantilevering can be used for constructions as simple as bookshelves or as complicated as bridges.”
