Cantilever

A cantilever is a structural element that is firmly attached to a fixed structure at one end and is unsupported at the other end. Sometimes it projects from a vertical surface such as a wall. A cantilever can be in the form of a beam, plate, truss, or slab.

When subjected to a structural load at its far, unsupported end, the cantilever carries the load to the support where it applies a shear stress and a bending moment.[1]

Cantilever construction allows overhanging structures without external support.
