A study of kinetic friction: The Timoshenko oscillator [PDF]

open access: yesAmerican Journal of Physics, 2018
Friction is a complex phenomenon that is of paramount importance in everyday life. We present an easy-to-build and inexpensive experiment illustrating Coulomb's law of kinetic friction. The so-called friction, or Timoshenko, oscillator consists of a plate set into periodic motion through the competition between gravity and friction on its rotating ...

Static and kinetic friction of rapeseed [PDF]

open access: yesResearch in Agricultural Engineering, 2007
he present paper examines the static and kinetic coefficient of friction of rapeseed. The project utilized two methods of determination of coefficient of friction of rapeseed: according Eurocode 1 (kinetic) in direct shear test and (static) in model silo.

Developing Smart Measurement Device to Measure Kinetic Friction Coefficients of Bi-Tilt Isolator

open access: yesAdvances in Civil Engineering, 2019
A sliding vibration isolation system, affected by a kinetic friction force, provides a flexible or energy dissipation system for a structure. The kinetic friction coefficient of the contact surfaces between the moving parts changes with the relative ...

Quantum “contact” friction: The contribution of kinetic friction coefficient from thermal fluctuations

open access: yesFriction, 2023
A thermal model of kinetic friction is assigned to a classical loaded particle moving on a fluctuating smooth surface. A sinusoidal wave resembles surface fluctuations with a relaxation time. The Hamiltonian is approximated to the mean energy of the wave

The Kinetic Friction of Snow

open access: yesJournal of Glaciology, 1988
AbstractThree components of the kinetic friction of snow are described but only the lubricated component of friction is treated in detail. This component depends upon the thickness of water films which support a slider on snow grains over a small fraction of its area.

A novel method for determination of kinetic friction coefficient using inclined plane

open access: yes, 2021
Presented in this paper is the theoretical background for a novel method for determination of kinetic friction coefficient. The method is based on the equation of movement of a rigid body along an inclined plane and has not been previously discussed in ...

Tuning static drop friction

open access: yesDroplet, 2023
The friction force opposing the onset of motion of a drop on a solid surface is typically considered to be a material property for a fixed drop volume on a given surface.

Statistical approach on the inter-yarn friction behavior of the dual-phase STF/ρ-Aramid impregnated fabrics via factorial design and 3D-RSM

open access: yesHeliyon, 2023
Shear thickening fluids (STFs) refer to non-Newtonian fluids of the dilatant variety, wherein their viscosity experiences a significant surge with an escalation in the shear rate. In this investigative work, the friction behavior between yarns (pull-out)
