If a header is composed of two 2x12s, how many members does it consist of?

• A. one
• B. two
• C. three
• D. four

Answer: (B)

In the context of structural engineering and construction, a header typically refers to a beam that spans an opening, such as a door or window. When the question specifies that the header is composed of two 2x12s, it indicates that these two pieces of dimensional lumber are being utilized together to create the header. Each of the 2x12s counts as a single member. Therefore, having two of them means that the header consists of two structural members in total. This reflects the practice of stacking or reinforcing members to increase strength and load-bearing capacity, which is common in construction. Thus, the correct understanding leads to the conclusion that the header is made up of these two distinct members.
