Direct measurements of colloidal friction coefficients
Physical Review E, 2001The time-independent hydrodynamic forces operating between two hard spheres were studied as a function of the interparticle separation r. Two colloids were positioned a distance r apart using a dual-beam optical tweezer similar to that described by Meiners and Quake [Phys. Rev. Lett. 82, 2211 (1999)].

SummaryA summary is presented of information collected on coefficients of friction (rolling and sliding) between rubber tyres and road or runway surfaces. Nearly all the data collected are from tests on automobile tyres and are limited to speeds of about 40 m.p.h.

Coefficient of Friction of Watermelon
Transactions of the ASAE, 1996The static and dynamic coefficients of friction for two watermelon cultivars against six different surfaces were measured at three sliding speeds and three normal forces. The sliding speed, measurement (harvest) date, and type of abrasive surface had a significant effect on both coefficients, except sliding speed did not affect the dynamic coefficient ...

Coefficient of Friction of Human Corneal Tissue
Cornea, 2015A novel property evaluation methodology was used to determine the elusive value for the human corneal coefficient of friction (CoF).Using a microtribometer on 28 fresh human donor corneas with intact epithelia, the CoF was determined in 4 test solutions (≥5 corneas/solution): tear-mimicking solution (TMS) in borate-buffered saline (TMS-PS), TMS in ...

An eight-legged tactile sensor to estimate coefficient of static friction
Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2015It is well known that a tangential force larger than the maximum static friction force is required to initiate the sliding motion between two objects, which is governed by a material constant called the coefficient of static friction.

Geomembrane Coefficients of Interface Friction
Geosynthetics International, 1995The influence of soil particle shape, confining pressure and the amount of relative displacement on the value of the interface friction angle are studied in the laboratory using a ring shear apparatus. Two quartz sands, one angular and the other rounded, with two geomembranes, one soft and the other hard, were used as the interfacing constituents. The
