Which of the following best describes the function of a lintel in construction?

1. Is a term used only in relation to doors.

2. Essentially performs the same structural function as an archway.

3. Is used with exterior siding to ensure a minimum clearance is provided between the bottom of the siding and the finished grade level.

4. Must be constructed of steel in order to provide the needed support.

5. Is used to vent hot air from a fireplace.

6. Acts as an insulator in wall construction.

The correct answer is: Essentially performs the same structural function as an archway.

A lintel in construction essentially performs the same structural function as an archway. It is a horizontal piece of material (typically steel, concrete, or wood) that spans an opening such as a door or window. Lintels support the weight of the structure above the opening and help distribute the load to the vertical supports on either side of the opening. This ensures that the opening maintains its structural integrity and does not collapse. Therefore, option B is the correct answer as it accurately describes the function of a lintel in construction.
