hoeksverhouding
Hoeksverhouding, also known as the angle of repose, is a fundamental concept in geology and soil mechanics, referring to the maximum angle at which a granular material, such as sand or gravel, can remain stable without sliding. This angle is determined by the internal friction between the particles and the cohesion between them. The angle of repose is influenced by various factors, including particle size, shape, and moisture content. It is typically measured by placing a pile of the material on a flat surface and gradually increasing the slope until the material begins to slide. The angle at which this occurs is the angle of repose. This concept is crucial in understanding the stability of slopes, the design of retaining walls, and the behavior of granular materials in various engineering applications. The angle of repose is not a fixed value and can vary depending on the specific characteristics of the material and the environmental conditions.
