The Max Static Friction Force calculator computes the maximum force boundary between the Normal force and the friction force.

INSTRUCTIONS: Choose units and enter the following:

• (μ_s) Static force coefficient
• (F_N) Normal Force

Max Static Friction Force (F_{s max}):The calculator return the max static friction force in newtons.  However, this can be automatically converted to other force units via the pull-down menu.

The Math / Science

Static friction occurs between surfaces that are not slipping over each other. Slipping surfaces experience kinetic friction.

The formula for max static friction is:

F_{s max} = μ_s⋅ F_N

where:

• F_{s max} = max static friction
• μ_s = Static Force Coefficient
• F_N = Normal Force
