Follow @physics_unplugged | video description 👇 This is how non-spherical ball bearings are possible Traditional ball bearings rely on spheres for smooth, uniform motion, but certain non-spherical shapes can achieve similar functionality under the right conditions. With the help of Beau Janzen, who explains this concept through detailed visualizations, we see how equilateral shapes-such as Reuleaux triangles, rounded polygons, or specialized cam profiles-can function like rolling elements while
