Through dc regenerative braking, ac variablespeed braking, and ac servo braking are growing, friction devices, especially in small industrial applications, aren’t going anywhere anytime soon. More ...

Friction is immensely important to us – without it, for example, we could not walk or even crawl – yet it is only 50 years since a special word – 'tribology' – was first coined to describe its study.

Friction is so common in our daily lives that we barely think about it. Humans have been forced to deal with it since prehistoric times: the wheel is essentially a device for reducing friction when ...

You've got the golden armadillo? Quick, go before the dragon catches you! It could be here any minute – why aren’t you moving faster? Friction? You mean the force between the surface of the road and ...

Irregularities present on a surface are often described as surface roughness or texture. These surface textures such as grooves and dimples impart friction, which is the force between two sliding ...

Friction is a force that opposes motion. It is present whenever two surfaces rub over each other, such as when you rub your hands together, or when you apply the brakes on a bike or in a car. Friction ...

The coefficient of Friction of a material is the measure of the sliding resistance of a material over another material. In the case of thermoplastics the mating part is normally steel. When ...

Despite the looming ecological consequences, glacier motion remains poorly understood. The bedrock, the ice-bed interface and the water-filled cavities all affect friction and influence how the ice ...
