8. Rise over Run
The ratio of vertical rise to horizontal run constitutes the fundamental principle underlying any inclined plane steepness determination. This relationship, commonly expressed as “rise over run,” directly dictates the calculated gradient and, consequently, the suitability of the slope for its intended application.
-
Definition of Rise and Run
Rise represents the vertical distance traversed along the slope, measured from the starting point to the endpoint. Run signifies the corresponding horizontal distance covered during the same interval. The quotient of these two measurements establishes the gradient, quantifying the steepness of the inclined plane. For example, a rise of 1 meter and a run of 12 meters yields a gradient of 1/12.
-
Impact on Gradient Calculation
Variations in either the rise or run directly influence the calculated gradient. An increase in rise, while maintaining a constant run, elevates the gradient, resulting in a steeper incline. Conversely, an increase in run, while maintaining a constant rise, reduces the gradient, yielding a gentler slope. The precise measurement of both rise and run is therefore essential for accurate determination of the inclined plane steepness.
