A structural member used to form a roof or floor framework; it typically forms triangles to provide maximum strength with minimal material is called a what?

• A. Ridge
• B. Reinforced concrete
• C. Stud
• D. Truss

Answer: (D)

A truss is a structural framework made up of members arranged in triangles to provide maximum strength with minimal material. This triangular arrangement distributes loads efficiently, allowing roofs or floors to span wide distances while using less material and staying rigid under varying stresses. The rigid triangular units resist both compression and tension, preventing bending and sagging that would occur with simple beams.

The other options don’t fit this description. A ridge is the top edge of a roof, not a framing system. A stud is a vertical wall member, not a roof or floor framework. Reinforced concrete is a material, not the triangular framing arrangement used to span spaces in roofs or floors.
