Static Friction Coefficient Is Not a Material Constant [PDF]
Physical Review Letters, 2011 The static friction coefficient between two materials is considered to be a material constant. We present experiments demonstrating that the ratio of shear to normal force needed to move contacting bodies can, instead, vary systematically with controllable changes in the external loading configuration.

A Tactile Sensor Using Piezoresistive Beams for Detection of the Coefficient of Static Friction [PDF]
Sensors, 2016 This paper reports on a tactile sensor using piezoresistive beams for detection of the coefficient of static friction merely by pressing the sensor against an object. The sensor chip is composed of three pairs of piezoresistive beams arranged in parallel

A Novel Method to Measure the Static Coefficient of Friction for Socks [PDF]
Sensors, 2022 Mechanical testers have commonly been used to measure the frictional properties of socks. However, the friction values may be susceptible to the level of stretchiness of tested fabrics or human variability. Thus, the aim of this study was to propose a novel method that enables friction measurement of socks in a sock-wearing condition with less human ...

The calculation of kinetic and static friction coefficient and friction graph analysis using Arduino [PDF]
Physics Education, 2020 Abstract In this study, with the help of the Arduino UNO and load-cell force sensor, a simple experimental material has been developed to calculate kinetic and static friction coefficients and analyse the friction force in detail. The system with a force sensor mounted on it is placed on the plane.

Static Friction Coefficient Depends on Geometry [PDF]
Journal of TribologyAbstract Classical theories state that the friction coefficient is independent of geometry, depending only on the real contact area determined by roughness. However, experimental evidence shows significant differences between static and dynamic friction coefficients.

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015 We consider the effect of differing coefficients of static and dynamic friction coefficients on the behaviour of contacts involving microslip. The classic solutions of Cattaneo and Mindlin are unchanged if the transition in coefficients is abrupt, but if
