Prediction of slips: an evaluation of utilized coefficient of friction and available slip resistance

Ergonomics, 2006
The purpose of this study was to investigate the relationship between measures of floor surface slip resistance and an individual's peak utilized coefficient of friction (COFU) on the probability of a slip occurring during level walking. Video, kinematic and ground reaction force data were recorded simultaneously as subjects walked at a self-selected ...

FRICTION AND ROLLING RESISTANCE COEFFICIENTS OF FIG

Acta Horticulturae, 1998
The coefficients of friction and rolling resistance on various surfaces have great importance for designing agricultural machinery. In this research, two different methods were used. Rolling resistance or maximum angle of stability appearing during the rolling of fruits was measured on an inclined plane.

Friction coefficient determination by electrical resistance measurements

Physics Education, 2018
Abstract A simple and low-cost, DIY-type, Arduino-driven experiment is presented for the study of friction and measurement of the friction coefficient, using a conductive rubber cord as a force sensor. It is proposed for high-school or college/university-level students. We strongly believe that it is worthwhile planning, designing and

Method of evaluating the coefficient of friction of frost-resistant sealing rubbers

Journal of Friction and Wear, 2016
The results of an experimental study of the effect of the normal pressure in the range of 0.1–0.3MPa, a velocity of sliding of 1–100 mm/s, and a bulk temperature of 22 to–27°C on the coefficient of sliding friction of an elastomer–steel friction pair have been presented.

COEFFICIENT OF FRICTION FOR FLOW RESISTANCE IN ALLUVIAL CHANNELS.

Proceedings of the Institution of Civil Engineers - Water, Maritime and Energy, 1999
Conventional equations for predicting alluvial channel depths and velocities are primarily based on theory and experiments with channel boundaries which are rigid (rough) and impermeable. These equations rely on calibration of a reach-specific coefficient or a relationship between hydraulic roughness and a physical dimension of the elements forming the
