The friction between the finger pad/palm and items of sports equipment strongly influences how well an athlete is able to perform. It not only determines how well equipment can be gripped and manipulated, but also how the equipment feels to use and the perceived level of performance. In this paper various fundamental aspects of finger pad friction are reviewed, including the effects of applied force,...
The relationship between normal force and friction force for a finger contacting a surface was examined, and also the effect of surface roughness, using a finger friction rig. To investigate the normal force–friction force relationship 12 materials were used: 3 metals, 5 plastics and 4 elastomers. Forty tests were carried out across a range of loads, for each material. The roughness tests were run...
Handling errors are often seen in professional rugby games and even more so in amateur rugby. This paper analyses the problem of ball mishandling using high-speed video footage of passes and a bespoke finger friction rig. The high-speed video analysis showed that when the ball is caught, often there is a fluctuating movement of the fingers over the surface of the ball. It also showed that the fingers...
A great deal of work has been carried out to investigate skin friction, most has been aimed at determining the effect of skin condition and driven by developers of cosmetic products who are interested in the measurement of dynamic coefficient of friction. Little work has been carried out to look at grip and static coefficients of friction.In this work a rig was developed for measuring finger friction...
