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?
