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.

Figure 4 shows the forces acting on the cylindrical thrust plate, including the resultant frictional force [F.sub.f], which is given by the sum of the oil film shearing force [F.sub.vs] and the solid shearing force [F.sub.ss]; the solid contact force [F.sub.sc]; the oil film force [F.sub.OIL]; the spring forces [F.sub.s]; and the gas forces [F.sub.po] and [F.sub.pi].
5 shows another trend of the frictional force. The extent of the oscillation decreases greatly.
The results of tribological characteristics such as the movement of the piston, the minimum film thickness, the frictional force and friction power loss were studied in relation to the viscosity lubricant.
The frictional forces are affected not only by the surface roughness but also by the material's stiffness [3], that is, contact forces between the two surfaces (i.e., the wire and the bracket) during sliding in frictional tests increase with increasing wire's stiffness [17].
Nyman [21] assumes that frictional force will reach its limit value when the pipeline-soil relative displacement increases to the yield displacement xu (generally at 3-10 mm).
When, the steel plate starts sliding over steel platform, then the force of gravitational pull is equal to the frictional force between steel plates [1-3].
Figure 5(a) showed a plot of the frictional force versus normal load at the same bias voltage [V.sub.e] of 0 V.
The model is able to consider variable frictional force of AFD.
However, frictional forces are rather low in shotshells.
Eventually, they jam tightly against the walls of the crevice, creating a frictional force that stops the climber's fall.
Cutnell and Johnson (2001) has explained the principal of shear along the discontinuity surface as when a normal load is acting on discontinuity surface and a load F is applied parallel to the surface that tends to shear then resistive frictional force fs has the following properties: The resistive force fs have equal magnitude as F (component of F parallel to the surface in case F is not parallel to the surface) butopposite in direction.
The shear angle is defined as the degree of angle that changes at peak frictional force and at the commencement of the experiment.
