The frictional force is a maximum in the initial portion of the film displacement (static region), so it can be expected that the erucamide transfer would be greatest near the startup region and lesser in the kinetic region.
Delayed compaction of the solids was due to the loose particulates originating from the feed section, requiring greater distances to develop the necessary frictional forces to fill the channel.
The frictional force needed to slide the polymer is used to break either the adhesion areas at the asperities (or simply adhesion asperities), the metal, or the polymer, whichever is easiest.
The frictional force is derived from the measured steady-state strain on a calibrated leaf spring attached to the counter-face and [Mu] is the ratio of the measured frictional force to the applied normal force.
At this point the frictional force will change because the pressure has dropped to near zero, and the solids will again convey via frictional forces.
The dynamic frictional force FD is the average force over the first 6 cm of movement after the start of relative movement between the surfaces in contact, neglecting the static force peak Fs.
Some previous coating formulations had an inverse relationship between their frictional force and the amount of particulates generated.
Nano-sized bumps on the surface of Nanofront raise frictional force and produce a surface area dozens of times greater than that of regular fiber, giving the material outstanding slip resistance.
Frictional resistance is an important consideration in orthodontic mechanotherapy because forces needed to retract teeth necessarily has to overcome the frictional force.
Expressions for the velocity, axial pressure gradient, pressure rise and frictional force over a one wavelength are obtained.
