In this 3-part series we look at the case of dry, sliding friction and discuss how surface roughness and materials impact the surface as a bearing. Download this 3-Part Series

We’ve had a lot going on related to ice lately! It is that time of year… A few months ago, we posted an article about the sport of curling, which

Want to maximize your fun while skating? Make sure that the ice temperature is -7°C! For many years I thought that concentrated pressure is what melts the ice when you

For surface roughness measurement, it would seem like “non-contact” methods would always be preferable. After all, being able to measure a surface with no possibility of contact damage would always

We wanted to take a moment to wish everyone a great season and happy new year. We’d like to express our gratitude for making it through all of the “peaks

Pierre-Gilles de Gennes, Françoise Brochard-Wyart, David Quéré, 2003 When I started the Surface Roughness, Texture and Tribology class some 20 years ago I searched for good descriptions of the physics

Tracking the ratio of several bearing ratio parameters can provide information about the symmetry of the surface texture, which can sometimes be more important than the amplitudes of the peaks

Benoit Mandelbrot, whose birthday we commemorate on November 20, found commonality in the math that describes patterns and distributions in nature and modern life. Mandelbrot saw order in phenomena that

The American Society of Mechanical Engineers’ ASME B46.1 standard defines surface roughness, waviness, and lay, as well as parameters for specifying and controlling surface texture. Learn what it covers and

Cutoffs define the band of spatial wavelengths that will be included in the calculation of surface texture parameters. Per specifications, the cutoffs must be specified. So, what do you do
