This simple device generates a rotational force using gravity and springs

I don`t know if this is an exploit, my theory is that the perfect springs (no thermal or energy loss) allow the downwards force to be transferred into the circle.

I did not copy this from anyone. If this was already posted, then sorry. I tried to search for something similar before. There is no weird spring forces, no weird density (the Purple extensions are lighter has to make the impusion faster, you can make them have the standard density and still work). Also, Hinges are not motorized at all

NO WRONG FILES THIS TIME ><
Just hit play and its done. Also, i think i should have named it Gravity Impulse Amplificator, since it doesnt starts unless you give it a little force
