friction

 [frik´shun]
the act of rubbing.

fric·tion

(frik'shŭn),
1. The act of rubbing the surface of an object against that of another.
2. The force required for relative motion of two bodies that are in contact.
[L. frictio, fr. frico, to rub]

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.

In the implementation of this algorithm, two issues have to be solved: event detection and static friction computation.
These results, which are in excellent agreement with the numerical simulations performed by the Italian team, show that static friction cannot only be suppressed, but also generated as desired if the contact pressure between the two surfaces is increased.

After a certain amount of time, the payload will start sliding because the extraction force exceeds the maximum static friction force.
These should account for the static friction and the variability of friction especially with the vertical load, which makes the friction force different from one device to another.
When [F.sup.([alpha]).sub.s] cannot overcome the static friction force [F.sup.([alpha]).sub.f] (i.e., [absolute value of [F.sup.([alpha]).sub.s]] [less than or equal to] [absolute value of [F.sup.([alpha]).sub.s]]), mass [m.sub.[alpha]] does not have any relative motion to the belt, that is,
From the bifurcation and the duty cycle diagram, we can conclude as follows: when the maximal static friction torque is smaller, there is no sliding bifurcation and the stick motion cannot be observed.
As shown in Figure 9(c), the slip appears as the value of friction coefficient is more than the maximum static friction and the friction force changes its direction when the values of [C.sub.e2] are 8 Nm and 10 Nm.
I have used one now withdrawn method, D4518, "Measuring static friction of coating surfaces" many times.
The total power is transferred through the rotor, one part of the total power comes from static friction dragging of the rotor surface, and the other part is attributed to the positive conveying of the rear vane and the front vane.
The dependence of the static friction coefficient on load under a speed of 100 mm/min: 1--friction between paper and print made using conventional inks, 2--friction between paper and print made using UV inks, 3--friction between paper and plane paper.
