So I’m trying to measure the ratio between two unknown masses using a compound lever. Provided below is a link to the photo of the machine that I’m using. I was able to balance the two masses between the First Class and Second Class levels but I cannot figure out how to determine The ratio between the two. In my design, I’m always putting the larger massed object within the contraption’s stand and the lighter massed object on the arm that extends out. Can anyone provide me a formula and explain how to determine the ratio of these two masses?

Looks like the door stopper is hanging about equal distance from the fulcrum as the other lever is attached. That should be give or take around a 1:1. The yellow thing, whatever it is, is about 1/3rd way between the end of the lever and the fulcrum, so 1/3 of its weight is being supported on the load side, and 2/3 near the fulcrum. So the full weight of the door stopper is roughly 1/3 the yellow thing… I think…
