1. What is Rise and Run Calculation?

Rise and run calculation determines the vertical and horizontal components of a ramp or slope. The rise represents the vertical height change, while the run represents the horizontal distance covered by the ramp.

2. How Does the Calculator Work?

The calculator uses trigonometric formulas:

\[ \text{rise} = \text{Length} \times \sin(\theta) \] \[ \text{run} = \text{Length} \times \cos(\theta) \]

Where:

Length — The total length of the ramp (meters)
θ — The angle of the ramp in degrees
sin(θ) — Sine of the angle (unitless)
cos(θ) — Cosine of the angle (unitless)
rise — Vertical change (meters)
run — Horizontal change (meters)

Explanation: These formulas break down the ramp length into its vertical and horizontal components using basic trigonometry.

3. Importance of Rise and Run Calculation

Details: Accurate rise and run calculations are essential for ramp design, construction planning, accessibility compliance, and slope analysis in various engineering and architectural applications.

4. Using the Calculator

Tips: Enter the ramp length in meters and the angle in degrees (0-90°). All values must be valid (length > 0, angle between 0-90 degrees).

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for the calculations?
A: The calculator uses meters for both length and results, but you can use any consistent unit system as long as you maintain consistency.

Q2: What is the maximum angle allowed for ramps?
A: For accessibility, the maximum recommended slope is typically 4.8° (1:12 ratio). Steeper slopes may be used for specific applications but require careful consideration.

Q3: Can I use this for other slope calculations?
A: Yes, these formulas work for any right triangle where you know the hypotenuse length and one angle.

Q4: How accurate are the results?
A: The results are mathematically precise based on the trigonometric functions, with rounding to 4 decimal places for practical use.

Q5: What if I know the rise and run but need to find the angle?
A: You can calculate the angle using the formula: θ = arctan(rise/run), then convert from radians to degrees.
