Coefficients Of FrictionRoy Mech
The friction resistance is almost independent of the specific pressure between the surfaces. At low pressures the friction varies directly as the relative surface speed At high pressures the friction is high at low velocities falling as the velocity increases to a minimum at about 0 6m/s. The friction then rises in proportion the velocity 2.
