Angle of Repose Calculation

Introduction to Angle of Repose Calculator

The angle of repose refers to the steepest angle at which a pile of unconsolidated granular material remains stable. It is determined by the friction properties between the particles. The formula calculates the angle of repose (θ) using the friction angle (μ). The result is in degrees, and it indicates the slope angle at which the material remains stable.

Parameter usage:

• frictionAngle = friction angle in radians or degrees

Output:

• θ = angle of repose in degrees

Data validation

The friction angle should be in the range between 0 and π/2 radians (0 and 90 degrees). The formula uses Math.atan to calculate the arctan, so it is able to handle the range of valid input values.

Summary

This calculator allows the determination of the angle of repose based on the friction properties of granular material. The result is a valuable parameter for understanding the behavior of granular materials under different conditions.
