The building load is supported by the surface friction between the pile and the soil.
Above the surface friction layer, lines of θ, B, and streamlines are nearly parallel.
Higher loop density will increase the surface friction as well as unevenness of the sewing thread surface.
The particle smoothness was measured on artificial leather based on KES-SE objective evaluation of the surface friction (Kato Tech Co., Ltd).
The effects of the scarf angle, the surface friction and the clamping force are investigated in detail.
We noticed that non-uniform double helices can be produced due to the surface friction induced by the self-contact.
In summary, when the surface friction is large enough to prevent the fingertip from smoothly sliding on the contactor, the effect of lateral vibrations is not expected.
The surface friction tester is a small fifth wheel attached to a hydraulic system mounted on the rear axle of the vehicle, used to measure road slipperiness.
The vehicle can relay the surface friction data back to the control centre, allowing gritting and clearing to be planned so that the vehicles are deployed most efficiently.
The sensors are usually mounted to small compact or estate cars or to a small trailer, rather than the large trucks used for other winter service equipment, as the surface friction tester works best when attached to a lightweight vehicle.
