🏔️ Angle of Repose Calculator
Calculate the maximum angle at which granular materials can be piled
📐 Angle of Repose Formulas
θ = arctan(μ) = arctan(F_f/N)
μ = tan(θ) = F_f/N
F_f = μ × N = μ × mg × cos(θ)
Stability Factor = μ/tan(θ_actual)
θ = angle of repose, μ = coefficient of friction, F_f = friction force, N = normal force

💡 Tips & Information
- Angle of repose increases with particle size and angularity
- Moisture content significantly affects stability
- Compaction increases the angle of repose
- Used in mining, construction, and material handling
- Safety factor should be ≥ 1.5 for practical applications
