Hi Nwman,
I love these little puzzles.
OK, it cannot work and here is why:
The weights when horizontal both weight 1Kg, but because they are in balance their rotational weight is zero.
The two weights are 1m apart.
If you move the right hand weight 10cm to the right so you have an imbalance.
Relatively speaking, the weight on the left weights 100% of 1Kg and the weight on the right weights 110% of 1Kg.
Result weight is 1 - 1.1 = 0.1Kg
(you can test this part with some kitchen scales couple of weights, bit of string and a ruler with a hole drilled in the centre)
When the weight gets to the bottom you have to lift it 10cm and it weights 1Kg thanks to gravity.
When the weight gets to the top again you need to lift it 10cm and it still weights 1Kg.
Can you see where this is going....
You are gaining 0.1kg of downforce maximum but you are still lifting a full 1Kg of weight top and bottom.
I feel sorry for the mechanic, wasting all his money on a big wheel. Such a pity.
