A truss is a construction made up of parts arranged in linked triangles such that the whole thing acts as if it were a single item. Bridges, roofs, and towers are the most typical uses for trusses.
A truss is constructed out of a web of triangles that are connected together to distribute weight evenly and handle shifting tension and compression without bending or shearing. When compared to a four (or more)-sided form, the triangle is mathematically stable since the corner joints must be secured to avoid shearing.
Trusses are made up of triangular units with straight members. Joints, also known as nodes, link the ends of these components.
