Cantilever arms are structural elements that extend horizontally and are supported only at one end, allowing for overhanging structures without the need for additional supports. These arms are commonly used in architecture and engineering to create vast open spaces and unique designs, as they provide a sense of openness and freedom within a structure. Cantilever arms are crucial in the design of bridges, buildings, and even furniture, as they allow for the creation of visually striking and functional spaces. Their ability to defy gravity and create a sense of weightlessness adds an element of intrigue and elegance to any design. Whether used in modern skyscrapers or iconic architectural landmarks, cantilever arms are a testament to the ingenuity and creativity of human engineering.
