Cantilever refers to a beam or structural element that is fixed at one end and free at the other, allowing it to project out without external support on its free end. Cantilevers rely on the principle of balancing moments, where the fixed end resists bending and shear forces to support the load on the free end. They are commonly used in structures like balconies, bridges, overhangs, and cantilevered roofs, where space or design requirements prevent the use of intermediate supports. Cantilevers are highly efficient because they allow for large spans without compromising usable space underneath. In construction, they can be made from materials like steel, reinforced concrete, or timber, depending on the load and span requirements. Cantilever structures are particularly useful in modern architecture, enabling bold and visually striking designs. Engineers must carefully analyze the deflection, bending moments, and stresses to ensure the cantilever remains safe and functional under various loads. Proper design and material selection are critical, as cantilevers are susceptible to significant bending forces. Advances in engineering and material technology have made cantilevers a key element in innovative architectural and structural solutions.
