Like other structural elements, a cantilever can be formed as 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 additional support.
A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end (called cantilevers).For small footbridges, the cantilevers may be simple beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete.
A flash photo freezes in time the extent of vibrations of a cantilever beam, exposure beyond flash reveals the whole path of the beam and creates an interesting effect with the lighting (which consists exclusively of a carefully positioned 1 watt LED flashlight).
The vibration of a beam, such as this cantilever made of borosilicate glass, can be described with the Euler-Bernoulli beam equation alongside a loading function which includes inertia, gravity, and possibly drag, and functions describing the variable section modulus and linear density.
Euler–Bernoulli beam theory (also known as engineer's beam theory or classical beam theory) [1] is a simplification of the linear theory of elasticity which provides a means of calculating the load-carrying and deflection characteristics of beams.
The 4,142-square-foot cantilevered post-and-beam structure, nestled in a woodsy hillside with canyon and coastline views, went on the market for $12 million in April. With four bedrooms and three ...

In this case, the equation governing the beam's deflection can be approximated as: = () where the second derivative of its deflected shape with respect to (being the horizontal position along the length of the beam) is interpreted as its curvature, is the Young's modulus, is the area moment of inertia of the cross-section, and is the internal ...
