A lattice truss is a structural framework made up of interconnected triangles, designed to support loads efficiently. This design minimizes material use while maximizing strength, making it ideal for bridges, roofs, and towers. The triangular shapes distribute forces evenly, reducing the risk of failure under stress. Lattice trusses can be constructed from various materials, including wood, steel, and aluminum. They are commonly used in engineering and architecture due to their lightweight nature and ability to span large distances. Notable examples include the Eiffel Tower and many modern sports stadiums.
