Interactive video lesson plan for: Ball and Roll Bearings - Easing Resistance for Turning

Activity overview:

Invention by Leonardo Da Vinci, this is a solution to resolve the issues of friction. To bear the thrust of a vertical axle, which carries a heavy load, both the ball and roll bearings could be used. Leonardo also stated in his notes that the number of spheres should always be three and not four. If four spheres were used, they might not always touch the pivot and not move equally which would actually produce greater resistance!
