Coefficients of static and kinetic friction

  1. Oct 2, 2006 #1
    Suppose that the coefficients of static and kinetic friction have values such that the static coefficient is twice the value of the kinetic coefficient for a crate in contact with a cement floor. Does this mean that the magnitude of the static frictional force acting on the crate at rest would always be twice the magnitude of the kinetic frictional force acting on the moving crate? Give your reasoning.

    Yes, if the coefficients are a ratio of two, so will be the ratio of the forces. F=umg.
