What is the term for an overhang beam that projects beyond its support?

The term for an overhang beam that projects beyond its support is "cantilever beam." A cantilever beam is specifically designed to be supported at one end while extending outwards, allowing for unsupported lengths to project beyond its supporting structure. This design is often utilized in various forms of construction and architecture, such as balconies or bridges, where the beam must span distances without additional support beneath it.

This characteristic of a cantilever beam enables it to bear loads and provide structural stability while also allowing for the aesthetic and functional advantages of extending spaces or creating open areas. Understanding how cantilever beams work is crucial for structural engineers and architects to ensure that designs are both safe and effective.
