PurePower, I know you hate to talk about the lever, but if it as you say, and weighted towards the long end, then how is it that in the video, the long end is up, and the short end is down? if the long end is truely heavier, it should be on the ground.
No problems. I said if anyone still had questions I will still provide my input. Im just not going to go there myself...
Okay, its like this. Im going to use archaic Archurian math here, not dealing with torque, energy, or anything of the sort. Everything will be described in "kilos" even if it is not mass...
We have a small mass(1 kilo) a large mass (20 kilo) and a lever (15.5 kilo advantage towards the extended end).
Okay, so with the no mass on, the lever would fall to the extended end with 15.5 kilos. Now we add the heavy 20 kilo mass. Now the lever would fall to the short end with 4.5 kilos. Still with me? Good...
This is how the lever is weighted towards the long end, but it is still up in the video.
Now we add the 1 kilo to the 5:1 lever. This means we are getting 5 kilos lift at the short end. Since the short end is only down because of 4.5 kilos, the 1 kilo would easily fall to the round, lifting the 20 kilo mass.
Still believe in magic?
