cantilever

     

A cantilever is a beam supporte on only one end. The beam carries the load to the support where it is resisted by moment and shear stress. Cantilever construction allows for overhanging structures without external bracing. Cantilevers can also be constructed with trusses or slabs.

Trivia about cantilever

  • A bracketed projecting beam supported on only one end, or a type of bridge
  • (Cheryl of the Clue Crew stands outside the Robie House in Chicago, IL with a view featuring a broad roof overhang.) Steel beams let Wright build a daring example of this type of roof that extends beyond its supporting wall
  • Spanning 1,800 feet, the Quebec Bridge is the world's longest bridge of this type
  • (Kelly of the Clue Crew does a demonstration with a piece of paper.) Paper can be used to illustrate an architectural concept; holding the edge doesn't inspire much confidence in its structural integrity, but curve it, & you get one of these projecting structures with a simple machine in its name
  • A type of bridge, or any horizontal construction that projects out past its vertical support
