Researchers have uncovered key features of the dynamics of "stick-slip," a form of jerky motion responsible for squeaks and squeals in phenomena from door hinges to shifting tectonic plates. In this ...

Working together to study friction on the atomic scale, researchers at UC Merced and the University of Pennsylvania have conducted the first atomic-scale experiments and simulations of friction at ...

(Phys.org)—A new, noninvasive, and low-cost method for the early detection and monitoring of osteoarthritis (arthritis caused by wear and tear) may be on its way, thanks to research by UC Santa ...

Nanomachines will depend on our knowledge of friction, heat transfer and energy dissipation at the atomic level for their very survival. In the scramble to revolutionize the world with nanotechnology ...

Stick-slip chatter commonly shows up on initial start of a machine when static friction in the bearings temporarily restrains shaft rotation. As the shaft then winds up, torsional force rises until it ...
