In the above animation we can see how the Arabic wheel works. The blue rods have joints that allow them to bend in one direction. The longer the rod stands, the bigger the leverage. You can try this at home with a folding ruler; it's much harder to hold it once it's unfolded due to leverage (ie. counterweight). This effect should then be able to force the Arabic wheel shown above to keep turning from left to right.

This picture shows the leverage force on a straight and a bent rod, as stated above, the force is higher as the rod gets longer.

Concepts like the Arabic wheel are quite old. The one you see in the animation above has been submitted by a great thinker of our time who wants to be known simply as “Reno S”.

Why does this design fail as a perpetual motion machine?
