The traditional style of cross-country skiing works on the same principle — the downward kick stroke requires high static friction, while the glide is possible thanks to low dynamic friction.

Here, a poly styrene-co-butyl methacrylate) poly styrene-co-butyled on poly styrene-co-butylgh static friction at the interface between a coating and e.g. a wood pallet.
Electro-hydrostatic actuators offer faster control speeds but suffer from higher static friction levels when compared with open hydraulic circuits.
The fault contains two regions with different mechanical behaviours: a strong region (asperity) with a high static friction and a velocity-weakening dynamic friction and a weak region with a negligible static friction and a velocity-strengthening dynamic friction.
This showed that the quantitative component (higher resistance and higher static friction) matched the qualitative component of our survey (slow flashback and sticking of the catheter to the needle) which resulted in a clear preference of one cannula over another.
Especially, under the aborted take-off condition, the friction coefficient of the domestically developed carbon brake disc was 21-48% higher and the static friction coefficient was 28% higher than that of the ones provided by the aircraft manufacturer.
The highest static coefficient of friction was found on the plywood surface.
The present paper experimentally investigates the prospects of using surfaces with carefully designed topography to design contacts with a high level of static friction.
More importantly, it is predicted that, for high kurtosis values, the static friction coefficient decreases with decreasing external force rather than increasing as seen with increasing skewness.
