The Coefficient of Friction of Soccer Balls

open access: yesProceedings, 2020
Nine soccer balls were tested for their friction against a leather sheet, using a force plate. An average normal force of 63.6 N was applied and the movement of the ball had an average velocity of 15 mm/s.

Analysis of the Variation of Friction Coefficient of Sandstone Joint in Sliding

open access: yesAdvances in Civil Engineering, 2020
The friction coefficient of rock joints is closely related to the stability of the slope. However, it is difficult to predict the friction coefficient due to the influence of surface roughness and mechanical properties of rocks.

Efficiency of polymer materials in highly loaded systems in the aviation industry

open access: yesAviation, 2023
The static coefficient of friction was calculated on an inclined plane tribological stand. Different specimens and masses loading the system were used during the experiment. Surface-to-surface contact was tested in a pin-on-plate setup.

Nanofriction behavior of cluster-assembled carbon films [PDF]

open access: yes, 2002
We have characterized the frictional properties of nanostructured (ns) carbon films grown by Supersonic Cluster Beam Deposition (SCBD) via an Atomic Force-Friction Force Microscope (AFM-FFM). The experimental data are discussed on the basis of a modified

Shear Thickening of Dense Suspensions: The Role of Friction [PDF]

open access: yes, 2019
Shear thickening of particle suspensions is characterized by a transition between lubricated and frictional contacts between the particles. Using 3D numerical simulations, we study how the inter-particle friction coefficient influences the effective ...
