Researchers in China have isolated the effects of electronic friction, showing for the first time how the subtle drag force ...

Learn how to calculate the coefficient of friction on inclined planes in this physics tutorial. Step-by-step explanations cover the forces, equations, and reasoning you need to solve friction problems ...

Performance and usability nurture trust in real time, often before a customer even speaks to a person. When an online journey ...

A simple one-piece sleeve is sometimes better for reducing friction than complex rolling-element bearings. Besides being greaseless, journal bearings can be made out of high-tech plastics for weight ...

I learned to respect friction, as a phenomenon with many nuances, when I was a graduate student. One day, while teaching a problem session in elementary mechanics, I unwisely invented a new problem to ...

The concepts of friction and wear are easy to understand, yet they can interrelate in complex ways within a tribological system (science concerned with interacting surfaces in relative motion ...
