Coefficient of friction for a sphere
American Journal of Physics, 1984A ball that rolls on parallel tracks, whose width is less than the diameter of the ball, experiences both translational and rotational motions. The linear accelerations of the ball for cases of rolling and slipping are derived theoretically, and these accelerations have also been determined by performing experiments when the width and the angular ...

The coefficients of friction and wear
Il Nuovo Cimento, 1958The combination of the Savage surface energy and the Bowden and Tabor junction formation mechanisms of production of frictional energy is suggested. The physical description of the experiments is sufficiently simplified and represented by a stable state which envelopes the whole field of friction.

The coefficient of friction of metals
Wear, 1958Abstract To explain the increase in the area of contact, and hence in the adhesion, of a steel ball sliding on indium, McFarlane and Tabor produced an analysis based on the interaction of the normal and tangential stresses applied during sliding.

THE ordinary static friction apparatus with one mass m hanging over a pulley and connected to another mass M resting on the friction board may be used to determine the kinetic coefficient. Let m be more than sufficient just to move M, and let h be the vertical height over which m is allowed to accelerate M; then, if x is the extra distance along the ...

On the dynamics of the friction coefficient
Wear, 2003Abstract The paper deals with the principal wear mechanism in brake systems and introduces a new dynamical model of the friction coefficient, where necessarily both friction and wear are taken into account. This model explains many open questions on the principal functionality of brake systems.

The coefficient of friction for yarns
Journal of the Franklin Institute, 1936Abstract In view of the importance of the frictional characteristics in the manufacture of yarns and in the final appearance of textile products, a method has been devised with which it is possible to determine the coefficient of friction of individual yarns in absolute figures.

Skin-friction coefficient is analyzed with consideration of variable physical properties. The skin velocity gradient is the only one unknown variable for evaluation of the skin-friction coefficient. Systems of numerical solutions on the skin velocity gradient are obtained with consideration of variable physical properties.
