THE COEFFICIENTS OF STATIC AND KINETIC FRICTION USING ARDUINO

Jurnal Pena Sains
The friction coefficient plays an essential role in various aspects of daily life. In transportation safety, the friction coefficient between vehicle tires and the road is critical for safety. In design and construction, friction between structural components contributes to building stability.

Aging of the frictional properties induced by temperature variations [PDF]

, 2010
The dry frictional contact between two solid surfaces is well-known to obey Coulomb friction laws. In particular, the static friction force resisting the relative lateral (tangential) motion of solid surfaces, initially at rest, is known to be ...

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Determination of melon seed physical parameters and calibration of discrete element simulation parameters.

PLoS ONE
To improve the accuracy of the Hami melon discrete element model, the parameters of the Hami melon seed discrete element model were calibrated by combining practical experiments and simulation tests. The basic physical parameters of Hami melon seeds were

Temperature Dependence of the Static Friction Coefficient of Common Recyclable Polymers

Journal of Undergraduate Reports in Physics, 2023
According to the classical adhesion explanation for the phenomenon of friction, the friction coefficient between two surfaces is defined as the ratio between the horizontal friction force exerted on each surface and the perpendicular normal force between each surface.

Irreversibble Bimolecular Reactions of Langevin Particles

, 2000
The reaction A+B --> B is studied when the reactants diffuse in phase space, i.e. their dynamics is described by the Langevin equation. The steady-state rate constants are calculated for both the target (static A and mobile B's) and trapping (mobile A ...

A Biologically‐Architected Wear and Damage‐Resistant Nanoparticle Coating From the Radular Teeth of Cryptochiton stelleri

Advanced Functional Materials, EarlyView.
The ultrahard teeth of mollusks that feed on rocky substrates contain a wear‐resistant coating on their surfaces consisting of densely packed mesocrystalline magnetic nanoparticles within an organic matrix. These coatings display significant hardness and toughness through their highly controlled mesocrystalline architectures.

Biomimetic Ion‐Orchestrated Hierarchical Armored Hydrogel Coating for Robust and Multifunctional Surface Protection

Advanced Functional Materials, EarlyView.
Inspired by the skin‐toughening mechanism of marine sponges, an ion‐orchestrated structural engineering strategy is proposed to regulate the surface microstructure of hydrogel coatings, enabling the in situ formation of a robust armor layer that enhances mechanical integrity and provides multifunctional protection by suppressing fouling attachment and ...

Static and dynamic friction coefficients in DEM simulations of viscoelastic particles

Chaos: An Interdisciplinary Journal of Nonlinear Science
Whereas the elastic Hertzian contact force with nonlinear damping gives rise to the overlap dynamics in the discrete element method, the precise physical meaning of tangential springs representing solid friction has remained obscure. Moreover, the well-known difference between the static and the sliding friction coefficient has often been ignored.
