Yes I could be lazy too! In order to relieve the the question of your design I could simply say that you have four wheels, two of each size Weights are transferred between them. we will call one size wheel #1 and the other #2
Now everyone knows the answer to 1x2=2/1 and that could be the end of it.
I do not do that because I am not so lazy to write it off that easy. I am unable to answer your direct questioning in good faith, as I am not sure they would be correct in my own mind.
EDIT: Here is something I just picked up on!
If the four wheels are to work in unison then ratio is irrelevant just as my little equation, they will and must equal!Here lies 1 problem, I have to calculate the ratio that will cause those connected weights to lift all other weights in the system.
