Friction is a complex subject that we have broken up into multiple modules in this course. Understanding friction is critical in wide-ranging applications, from automotive and aerospace, to rock climbing and curling. In many cases we try to minimize friction (to improve engine performance, for example), but in other cases a high degree of friction is essential (in brake systems, for example). The concepts have been studied since antiquity, and we continue to invest a great deal of effort and resources to understand and control friction today.

The first case we discuss is the simplest: dry friction, which occurs in systems without lubrication. In this module we discuss the basic mechanisms and physics of dry friction, and the methods we use to measure it. We look at the relationships between surface texture (surface roughness) and dry friction, introducing the concept of “real contact,” the actual meeting points of two interacting surfaces. Finally, we revisit some of the surface texture parameters that we discussed in previous modules and show how they relate to, and change with, dry friction.

Following this module we encourage you to watch the next modules on Lubricated Friction and Rolling Friction for a more complete view of friction.

Frequently Asked Questions

How long do I have access to the course materials?

You can view and review the lecture materials indefinitely, like an on-demand channel.

Can I take my courses with me wherever I go?

Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don’t have an internet connection, some instructors also let their students download course lectures. That’s up to the instructor though, so make sure you get on their good side!
