Sentence examples for changes of the friction from inspiring English sources
On the other hand, the estimation of the shear stress and the resultant calculations of the friction coefficient also include some uncertainties: the state and magnitude of stress during seismic rupture might not be the same as the static values, and dynamic changes of the friction coefficient and stress drop are not considered.
The estimation successfully described the change of the friction force, including the sudden change due to pull-in.
After the optimisation the influence of friction on the measurement is less than 0·5% per 0·1 change of the friction coefficient.
Friction and wear tests conducted under a normal load of 1 N with tungsten carbide and 100C6 steel balls show no significant change of the friction coefficient whatever the relative humidity during the test but an important wear resistance improvement is observed for both alloys.
The work also includes a comparison of changes in the friction coefficient for each set of process parameters applied in the synthesis of carbon coatings.
First, a calibration for the estimation was conducted, whose results are summarized in Fig. 6. Figure 6a shows the change of the measured friction in several haptic voltage conditions.
The changes in the friction of the areas electrically processed at a high voltage were higher than those observed for the mechanically processed areas.
Sun et al. tested the changes in the friction of the canine flexor tendon treated with lipid solvents and phospholipase C [ 23].
The results showed that the changes of both friction and anisotropy had a similar trend with the particle size enlarging in the dense assembly, which maintain stable when the size is less than 3.0 mm.
Dyspareunia can also be caused by a natural reduction in vaginal lubrication – a consequence of certain hormonal changes – that means the friction of penetration becomes unpleasant or painful.
