How to Evaluate Sliding Factor?

Sliding Factor evaluator uses Sliding Factor = Coefficient of Friction between Two Surfaces*Total Vertical Force/Horizontal Forces to evaluate the Sliding Factor, The Sliding Factor formula is defined as the factor of safety against sliding as the resisting forces (friction + passive) divided by the driving lateral force, and the minimum value should be 1.50. Where seismic loads are included, the minimum safety factor should be 1.10. Sliding Factor is denoted by S.F symbol.

How to evaluate Sliding Factor using this online evaluator? To use this online evaluator for Sliding Factor, enter Coefficient of Friction between Two Surfaces (μ), Total Vertical Force (Σ_v) & Horizontal Forces (ΣH) and hit the calculate button.
