To calculate the angle of repose, use the ratio of the height to the radius of the material pile and apply the arctangent function.
The Angle of Repose Calculator determines the steepest angle at which a material remains stable without sliding. It is commonly used in engineering, construction, and material science to assess the flow properties of granular materials such as sand, soil, or powders.
Knowing this angle helps in designing storage solutions, analyzing slope stability, and understanding material behavior.
Formula:
a = atan(h/r)
Variables:
| Variable | Description |
|---|---|
| a | Angle of repose (degrees) |
| h | Height of the pile (units) |
| r | Radius of the base of the pile (units) |
