The Virginia Tech Transportation Institute will use a truck-mounted Sideway-force Coefficient Routine Investigation Machine, or SCRIM, to measure pavement friction and possible slick spots on U.S.

Fig. 1 Overview of the OFN sensor. (A) Schematic diagram of the OFN sensing system; (B) Photographs of the output light when the sensor was untouched, (C) subjected to normal force, and (D) subjected ...

Fast-moving nanoscale systems offer the tantalizing possibility for rapid processing of materials, energy or information 1. Frictional forces can easily dominate the motion of these systems, yet ...

Researchers have demonstrated how to entirely suppress static friction between two surfaces. This means that even a minuscule force suffices to set objects in motion. Especially in micromechanical ...

Friction is the enemy of all things mechanical, and without regular maintenance, machinery service life becomes severely reduced until, ultimately, the machines cease to function. Anyone who owns a ...

Robots may soon mimic the human sense of touch, with advances in flexible tactile detection aiming to endow them with the ability to sense friction and slip. Polymer optical fiber knots are at the ...
