Define a truss.

Define a truss.

• A. an engineered, prefabricated roof or floor support structure
• B. a decorative lintel
• C. a vertical column in a wall
• D. a circular beam

Answer: (A)

A truss is an engineered framework used to support roofs or floors. It’s typically made of straight members connected at joints to form triangles, which makes the structure very stable and efficient at carrying loads. Trusses are often prefabricated off-site to precise specifications, then installed on the building, allowing quick, consistent, and strong roof or floor support. This is why the description of an engineered, prefabricated roof or floor support structure best captures what a truss is. The other options describe different elements—a decorative lintel, a vertical column, or a circular beam—which are not what a truss is.
