What is a collection of lightweight structural components joined in a triangular configuration called?

A collection of lightweight structural components joined in a triangular configuration is referred to as a truss. This design is characteristic because the triangular shapes facilitate the distribution of weight and resist deformation under load, making trusses particularly effective for spanning large distances without intermediate supports.

Trusses are commonly used in various construction applications, including roofs and bridges, due to their ability to manage both tension and compression forces effectively. The triangular configuration inherently provides stability and strength, allowing for the creation of structures that are both lightweight and robust.

In contrast, a beam typically refers to a horizontal structural component that supports loads, whereas a joist is a smaller beam that holds up floors or ceilings. A column serves as a vertical support structure but does not necessarily involve the triangular configuration seen in trusses. Each of these components plays a distinct role in construction, but the defining characteristic of a truss is its triangular assembly, which maximizes strength and stability in engineering design.
