Final answer:
A brick laid horizontally with its longer edge exposed or parallel to the wall surface is called a stretcher. This is the standard for brick laying, as opposed to a header, soldier, or rowlock, ensuring the structural strength of the wall. Option 2 is correct.
Step-by-step explanation:
A brick or other masonry unit laid horizontally in a wall with the longer edge exposed or parallel to the surface is known as a stretcher. This is the most common and strongest position for laying bricks because it maximizes the resistance to pressure and the bond between the bricks, which is especially important in achieving the structural integrity of the wall.
This contrasts with other brick laying techniques like the header, where the short end of the brick is exposed, the soldier, where the brick is placed vertically with the long, narrow side exposed, and the rowlock, where bricks are laid on their sides with the end facing out.
In masonry construction, when a brick or other masonry unit is laid horizontally in a wall with the longer edge exposed or parallel to the surface, it is called a stretcher. Stretcher bricks are commonly used in a row to create the main structure of a wall.
For example, when building a brick wall, the majority of bricks used will be stretchers. The exposed face of a stretcher brick is smaller compared to the face of a header brick, which is laid with the shorter edge exposed.
