Three major laws [1-3] of friction are taken into consideration such as the frictional force
is proportional to the normal load; the frictional force
is independent of the apparent contact area and the frictional force
is independent of sliding speed.
Both toolboxes have inertia, but the one with rollers will experience trivial frictional forces
against the floor.
The resulting frictional force
(F) stops the climber's fall.
Where s is coefficient of static friction and N isnormal load acting The value of equation 1 is transition and sliding starts when the value of F or component of F parallel to the surface ( WhenF is not parallel to the sliding surface) exceeds the value of equation 1 and for kinematics frictional force
s is replace by kinematics coefficient of friction k.
Materials with high frictional force
on the skin resulted in a high shearing load.
The frictional force
on the sliding surface of the bearing is
These coatings increase a device's lubricity, which reduces the frictional forces
between the device and other devices or the vascular tissue itself.
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.
Figure 5 shows the relation between pretension in bolts and frictional force
, which was derived based on an assumption that frictional moment resistance can be replaced by a couple of frictional force
Frictional resistance is an important consideration in orthodontic mechanotherapy because forces needed to retract teeth necessarily has to overcome the frictional force
With this design, the frictional force
of the O-rings helps to prevent the occurrence of creep and subsequent damage to the shaft of the pump upon which the bearings are fitted.
Open, non-contact linear encoders are increasingly used in measurement applications that require higher traversing speeds and operating cycles, as well as lower mechanical backlash and zero frictional force
induced by an encoder.
Expressions for the velocity, axial pressure gradient, pressure rise and frictional force
over a one wavelength are obtained.
The frictional force
and torque was recorded during the test.
The mechanical energy is predominately frictional force
in the stone mill, shearing force in the hammer mill, and shock force in the jet mill.
