Which component supports a stairway?

1. Stringer

2. Riser

3. Handrail

4. Tread

The correct answer is: Stringer

The stringer is the component that supports a stairway, serving as the structural framework that holds the treads and risers in place. It is typically a long, angled board that runs along the side of the stairs and provides stability and strength to the entire stair assembly. Stringers are crucial for maintaining the overall integrity of the stairway, as they help distribute weight and provide the necessary support for individuals using the stairs. Without stringers, the treads and risers would lack proper support, possibly leading to safety issues or structural failure. In contrast, the riser and tread are components of the stairway itself; the riser is the vertical piece between each step, and the tread is the part of the step that you walk on. A handrail is an accessory that provides safety and support when ascending or descending the stairway but does not contribute to the structural support of the stair system. Thus, while all these components are essential for a functioning stairway, only the stringer directly supports it.
