Da Vinci's Perpetual Wheel
Da Vinci designed many perpetual wheels similar to the one shown that would run completely on their own. Da Vinci later realized that a wheel of this nature is physically impossible because of the loss of energy due to friction. Either way, this Demonstration helps to put one of his hypothetical sketches into motion to display what it might look like if the perpetual wheel were possible.
