For machines with mechanical elements, friction is an unavoidable enemy. It is a major source of service failure and can reduce the lifespan of any machinery, from bicycles and cars to airplanes and ...

Going fast is important. I mean what would racing be without speed? But on the other side of the coin, going fast will end in dramatic fashion if you aren't able to safely set your car for each corner ...

Here’s the rub with friction — scientists don’t really know how it works. Although humans have been harnessing its power since rubbing two sticks together to build the first fire, the physics of ...

Conventional car brakes are built with one thing in mind, the purpose of stopping the car. Since this purpose is essential, a great deal of time and resources were invested in the evolution of such ...

Overturning conventional wisdom stretching all the way to Leonardo da Vinci, new research shows that how things break (fracture) and how things slide (friction) are closely interrelated. The ...

It makes sense to think that reducing the friction in an engine, transmission, axle, and transfer case, will result in more power available to the wheels. While correct in theory, several industry ...

The field of economics has long modelled itself after Newtonian physics. When physicists analyse a complex problem, they usually begin with the simplest version and neglect any complicating effects, ...
