friction

surface resistance to relative motion; the rubbing of one surface against another; discord, dissidence, antagonism, clash, contention: The disagreement caused a lot of friction between the friends.
Not to be confused with:
fraction – a number usually expressed as 1/2, 1/4, etc.; a part as distinct from the whole of anything; portion or section: He received only a fraction of what he was owed.

fric•tion

(ˈfrɪk ʃən)

n.
1. surface resistance to relative motion, as of a body sliding or rolling.
2. the rubbing of the surface of one body against that of another.
3. dissension or conflict, as between persons or nations, because of differing views.

fric·tion

(frĭk′shən)
The resistance to movement that occurs when two objects are in contact. It is friction, for example, that slows down a ball rolling on grass and causes the blade of a saw cutting wood to get hot. There is less friction between smooth surfaces than between rough surfaces. Friction can be reduced by using a lubricant such as oil or silicone.

Wikipedia defines tribology as "the science and engineering of interacting surfaces in relative motion" There are no hard and fast rules for evaluating a polymer's tendency to feed, because the criteria noted--shape, size, and randomness--interact, and frictional force depends on contact area even though the friction coefficient remains essentially the same for given polymers.
Key statement: A rubber composition for a tire tread including 100 parts by weight of a diene-based rubber and 5 to 150 parts by weight of carbon black having a nitrogen adsorption specific area N2SA ([m.sup.2]/g) of 80 to 150 and satisfying a relationship between a TINT (%) and dibutyl phthalate absorption DBPA (ml/100 g) of TINT (%)>1.4 DBPA (ml/100 g) and capable of increasing the frictional force without impairing the hysteresis loss.
The derived theoretical model permitted the calculation of the oil film pressure, the solid contact force, the fluid frictional force, and the solid shearing drag force.
We used a tensile instrument (INSTRON 5566C2511, Instron Japan, Kanagawa Japan) to measure the frictional force of cables in accordance with JIS K 7125.
The total frictional force on the piston skirt [F.sub.f], is given by the sum of two components, hydrodynamic friction [F.sub.fh], and contact friction [F.sub.fc]
The USM was driven by frictional force under the pre-load where wear of frictional materials was inevitable under dry friction with high frequency micro-vibration.
But in the present study only the influence of coefficient of friction, inflation pressure, and normal load on the modified tire resistance is considered for some specified tractive forces described as a coefficient of the maximum frictional force, namely [[mu].sub.p][F.sub.z].
Tests were performed using an Instron machine with the cross head speed set at 1 mm/min; the wire was pulled through the brackets for 2 min, and the maximum loading, that is, the static frictional force, was measured using a load cell of 5kN.
The constraining force along the axial direction of the buried pipeline such as the pipeline-soil frictional force influences the pipeline-soil coordinating subsidence slightly and so can be neglected when analyzing the pipeline-soil coordinating bending deformation during surface subsidence.
The result of measurement of the frictional force [F.sub.t] is an estimate of the actual value of the measured quantity (this corresponds on the dynamometer for component of force [F.sub.y] in the kinematic system of the machine tool); what for i-th measurement can be expressed by equation:
Probably due to less frictional force. [4] In a study evaluating the 3D orthodontic force system suggested that adding elastic ligation increased the forces in the 3 planes.
