Thanks everyone. I actually had some errors in the spreadsheet that underestimated the potential energy transfer. Fixed it for now.
Merry Christmas and Happy New Year.
Aha, nice page. With some of those trebuchet variants it seems like they are trying to optimize what I was saying.
Although some machines will be difficult to analyze:)
With the potential energy of a large mass (for example 50 kg at 10 meters high) I want to accelerate a smaller mass (5-25 kg) upwards. I see that simple mechanisms like pulleys, levers, and simple gears leave a lot of kinetic energy in the large mass when it reaches the ground.
Is there some...
