This is a challenge for everyone.i have consulted with many experts but all are confused.
I consult with some physics professor s in my area and they are confused only on one point that input is minimal and ball is completing one cycle after falling twicely then why there is no overunity.
However, the item is question is not the input energy, but the output energy for which your calculation is incorrect.Your potential energy calculation is correct for a non-counterbalanced weight, but the falling weight also has to lift the counterbalance weight and the energy required to do this should be subtracted from your calculation in order to show the minimal amount of output energy available from the seesaw.
The spoon,the minimal input is only 20 Joule if I take friction loss 10% but output is 200 Joule from a 10 kg falling ball from 2 meter height.so when ball will hit with upper part of tube at the time of tilting then kinetic energy is 200 joule.now minus the input 20 Joule from 200 JouleSo overall output is 180 Joule.But you are forgetting that the seesaw is getting back it's initial position without any extra energy so ball is again falling from 2 meter height then output is 200 Joule again.Why are you not considering the falling of ball at the time of reversing.
The spoon,answer is that the energy will be generated by the kinetic energy of ball not by system.the ball will work to press a piston generator not system.so when it fall down then obviously the counterweight will be lift up but the output will be not subtracted .In this mechanism ball is working to generate energy not device as device is working to increase the potential energy.The counterweight has already been lifted up otherwise how ball will fall down?
The spoon,I am very much surprised that how are you taking it.The ball is being lifted up but you are forgetting that the seesaw is balanced so input is no matter.The ball is not generating energy ,it very strange but is releasing 200 Joule energy or 400 Joule energy twicely and you say that it is not perfect all motion.will you please explain then what is perpetual motion or overunity?You yourself has contradictions in your post.
Ok but what about falling down of ball at the time of reversing.as the seesaw is getting back its original position without any extra energy.
Yes ,it is an another thread.
