friction

A soft tissue massage technique, which entails the use of small circular pressure strokes from the fingertips, thumb pads and palms, with the intent of mobilising stiff joints and enhancing the circulation of blood to tendons and ligaments.

fric·tion

(frik'shŭn)
1. The act of rubbing the surface of an object against that of another; especially rubbing the limbs of the body to aid the circulation.
2. The force required for relative motion of two bodies that are in contact.
3. A group of movements in massage intended to move superficial layers over deeper structures, to reach deeper tissues, or to create heat. Includes static, cross-fiber, with-fiber, and circular frictions.

Surface-to-surface contact exists between counterpart and specimen during friction process, and friction coefficient is set as 0.54 (0 wt% Zr[B.sub.2] particles) and 0.22 (5 wt% Zr[B.sub.2] particles) respectively according to our experimental results.

Wood samples with varying moisture contents were tested at different normal loads (10, 20, and 40 N) to reduce the test error, and friction pairs were formed between the different microtexture specimens and wood at different locations on the same piece of wood, as shown Figure 4b.

The coefficient of friction and wear of specimens was obtained by conducting experiments as specified in the TS 555 (1992) and TS 9076 standard (1991).

Such an emergency (friction) brake could be based on a fully enclosed friction pair which has to be able to operate at the extreme high temperatures generated during the emergency braking intervention.
Time for a rethink on automotive braking technology
Due to the roughness and hardness difference between the drill string and wellbore rock by surface contact, the general elastic bristle in the dynamic friction model should be the bristles on the wellbore, which, unlike these models, was assumed on the motion body plane contact.
