Watch the second episode of the microstructure series about Shape Memory Alloys: https://nebula.tv/videos/the-efficien... Friction plays a role in every mechanical system, from gears and bearings to tires on the road. In this video, we examine what friction is, where it comes from, and why different surfaces interact the way they do. We’ll explore static and kinetic friction, the effect of surface roughness, and how engineers can use friction to their advantage.
