In wall framing, which term describes the upright post that supports wall coverings?

• A. Purlin
• B. Stud
• C. Truss
• D. Ridge

Answer: (B)

Vertical members in wall framing that run from the bottom plate to the top plate and provide the backbone for wall coverings are called studs. They carry the load from the wall to the floor and ceiling structure and give you something to attach drywall or siding to. A purlin is a horizontal roof-support member, a truss is a complete roof-support framework, and a ridge is the top horizontal line where roof planes meet. So the upright post described fits the definition of a stud.
