The formula to calculate the handrail length (HL) is:
\[ HL = \sqrt{SL^2 + SH^2} \]
Where:
Handrail length is the measurement of the handrail needed to match the diagonal distance from the top of the stair set to the bottom. This length ensures that the handrail provides adequate support and stability for individuals using the stairs. It is important for safety and compliance with building codes.
Let's consider an example:
Using the formula to calculate Handrail Length:
\[ HL = \sqrt{120^2 + 80^2} \approx 144.22 \, \text{inches} \]
This means that the handrail length would be approximately 144.22 inches.
