In the case of friction of paraffin and skiing waxes (climbing wax and downhill wax), whose thicknesses were kept constant, μS was found to depend the penetration, whereas μK remained constant in general. (Fig. 1., 2, 3) When the penetration was kept constant and the thickness was varied, μS increased with increasing thickness while μK remained constant. When, kowever, the penetration was made larger or the air temperature was made lower, μK proved to increase slightly with thickness. (Fig. 5, 6, 7, 8, 9, 10) From early days, the behavior of these skiing waxes has been considered to be mysterious, but the above-mentioned data show that climbing ability coincides with the value of μS which varies with their penetration, film thickness or other factos, and that sliding ability depends upon μK on snow.Thus we can obtain a wax with large μS by adjustment of these factors maintaining the value of μK constant. The ability of these paraffin and skiing waxes can be explained from their frictionthickness diagram. (Fig. 7, 8, 11, 13, 12, 14)
