Growth of application of automatic transmissions in agricultural and construction machinery drivetrains or car gearboxes that takes place lately, leads to increased interest in the assembly by both ...

Friction is an intrinsic physical phenomenon to curling. Without it, objects in motion would move endlessly, without slowing down. This would cause many safety-related problems: Cars or trains could ...

This study investigated the concrete-to-concrete friction behavior under dynamic cyclic loading at different loading rates, vertical loads, and surface roughness. The present work answers essential ...

Frictional domains on a monolayer graphene. AFM topography (left), simultaneously obtained friction force image (center), and predicted ripple domains (right) of an exfoliated monolayer graphene on ...

Schematic illustration of Friction Force Microscopy (FFM). The AFM cantilever, a small diving board-like structure about 200 micrometers long, 50 micrometers wide, and 1 micrometer thick, has a sharp ...

Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, their internal forces compete, causing constant rearrangements that ...
