static friction coefficient

Static friction coefficient is a dimensionless number, the amount of force that resists motion that is on the verge of motion.

formula

\( \mu_s =   \frac {f_s}{F_n}\) 

Where:

\(\mu_s\) (Greek symbol mu) = static friction coefficient

\(f_s\) = static friction

\(F_n\) = normal force
