An eight-legged tactile sensor to estimate coefficient of static friction
2015 37th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 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. Therefore, knowing the coefficient of static friction is of great importance for robot grippers which wish to maintain ...

Study of the static coefficient of friction of fishing cordage on a friction gear drum
Journal of Friction and Wear, 2010Fiction interaction of fishing cordage and a friction gear drum under the preliminary displacement on the contact arc by 40–720° is studied. In all experiments, similar pressure of the cordage on the drum surface is ensured. Formulas for the static coefficient of friction are obtained for any angle of the contact arc.

Effects of Interfacial Strength and Roughness on the Static Friction Coefficient
Tribology Letters, 2014A finite element model is used to simulate sliding inception of a rigid flat on a deformable sphere under combined normal and tangential loading. Sliding inception is treated as the loss of tangential contact stiffness under combined effects of plasticity, crack propagation and interfacial slip.

A Simple Lab Exercise to Determine the Coefficient of Static Friction
The Physics Teacher, 2006This paper describes a quick, simple, and reliable physics lab exercise for determining the coefficient of static friction between common materials. Only a meter stick, a protractor, and samples of the materials are needed. A mathematical derivation is given to show why the method works.

Development of an elastomer with a high static or breakaway friction coefficient
Journal of Applied Polymer Science, 1988AbstractThis paper reviews the literature concerning the measurement of friction coefficients (μ) for elastomers and summarizes our data measured under static or breakaway conditions against epoxy painted steel using ∼ 176 psi contact pressure. Although largely related to missile launch system applications, the μ values presented are specific for ...

The Influence of Surface Temperature on the Coefficient of Static Friction
The Physics Teacher, 2019Friction is one of the common forces that affect our everyday life and one of the oldest problems studied in physics. An interpretation of its nature is included in all general physics courses, in both high school and college. The desire and need to better understand it guided a long list of scientists who devoted themselves to the study of friction ...

Determination of the static friction coefficient from circular motion
Physics Education, 2014This paper describes a physics laboratory exercise for determining the coefficient of static friction between two surfaces. The circular motion of a coin placed on the surface of a rotating turntable has been studied. For this purpose, the motion is recorded with a high-speed digital video camera recording at 240 frames s−1, and the videos are analyzed

The Effect of Polish Maintenance on Static Coefficient of Friction
2004The static coefficient of friction (μs) of polishes, measured by the James machine and ASTM D2047, provides a measure of the inherent slip resistance of the polish film. When in use, polish films are invariably modified by traffic and routine maintenance procedures that could, theoretically, change the inherent slip resistance of the film.
