Static Friction Coefficient

Written by Jerry Ratzlaff on . Posted in Dimensionless Numbers

static friction coefficientStatic friction coefficient ( \(\mu_s\) ) (dimensionless number) (also called coefficient of static friction) is the amount of force that resists motion that is on the verge of motion.

Static Friction Coefficient formula

\(\large{  \mu_s =   \frac {f_s}{F_n}  }\)         

Where:

\(\large{ \mu_s }\)  (Greek symbol mu) = static friction coefficient

\(\large{ F_n }\) = normal force

\(\large{ f_s }\) = static friction
