dry friction

The hand with the rubber glove created an unpleasant dry friction.

The dry friction of his leathery fingertips on her neck.

A connection between dry friction and flutter instability in a simple mechanical system has been discovered.

Dry friction is also responsible for the rope drag a climber has to overcome in order to move forward.

Dry friction resists relative lateral motion of two solid surfaces in contact.

Microtexture (MiTx) provides dry friction and is a desired road property.

Dry friction leads to an effective rope length smaller than the available length L and thus increases the impact force.

The use of oil was also inherent, unlike other clutches that still basically relied on dry friction, with lubrication to avoid overheating when slipping.

Unlike other resistive forces, such as dry friction, which is nearly independent of velocity, drag forces depend on velocity.

In conditions where creating sufficient water film are difficult (dry or very cold conditions) glide waxes will have dry friction components added.

Since MiTx has so short waves, it is preferably measured by dry friction brake tests rather than by profiling.

By using the equations of Euler-Eytelwein to describe the dry friction between the rope and the protection points, the rope drag can be calculated.

Dry friction can induce several types of instabilities in mechanical systems, which display a stable behaviour in the absence of friction.

NOTE: These 3 laws only apply to dry friction, in which the addition of a lubricant modifies the tribological properties significantly.

Coulomb friction, named after Charles-Augustin de Coulomb, is an approximate model used to calculate the force of dry friction.

Dry friction as used in wheel brakes, by using disks (classically made of leather) at the pivot of a lever, with friction forced by springs.

In reality it was Ludwig Prandtl who suggested in 1928 this model to describe the plastic deformations in crystals as well as the dry friction.

Dry friction is subdivided into static friction ("stiction") between non-moving surfaces, and kinetic friction between moving surfaces.

The original version features a 27T 540 "silver-can" motor, open planetary differentials front and rear, and non-adjustable double wishbone suspension with dry friction shock absorbers.

Recently, Bigoni and Noselli (2011) have experimentally shown that flutter and divergence instabilities can be directly related to dry friction, watch the movie for more details.

They independently presented the creep versus creep force relation for a cylinder on a plane or for two cylinders in steady rolling contact using Coulomb's dry friction law (see below).

The two regimes of dry friction are 'static friction' ("stiction") between non-moving surfaces, and kinetic friction (sometimes called sliding friction or dynamic friction) between moving surfaces.

Skiing over snow is a combination of both wet friction and dry friction: too much water will create "wet drag" (suction), while too little water will result in "dry drag" (friction).

Dry friction is often used in contact, and the ultrasonic vibration induced in the stator is used both to impart motion to the rotor and to modulate the frictional forces present at the interface.

When the rope is clipped into several carabiners between the climber and the belayer, an additional type of friction occurs, the so called dry friction between the rope and particularly the last clipped carabiner.
