Coefficient of Static Fraction

  1. Feb 6, 2014 #1
    Please could somebody explain how the coefficient of static friction can be quoted as a constant in tables etc?
    [itex]\mu_s = F_s/ R[/itex]
    In most cases the reaction force is constant but as I push the box harder the friction force increases.

    Is [tex]\mu_s [/tex] actually the coefficient of limiting friction? Or am I totally misunderstanding?
