Compound machine
This is the finished compound machine with all the gears, sprockets, chains, etc.
What we wanted out of this was to have the most mechanical advantage we could have and the best efficiency. In order to get the overall mechanical advantage we had to calculate all of the simple machines seperatly then calculate all of them together.

These are the calculations we made on the compound machine to get the mechanical advantage
IMA 26.9
AMA 8.3
EFF= 30%
The reason why our AMA is a lot lower than our IMA is because we had a lot of problems with the gears turning, we were using a large amount of wieght so we ended up twisting one of the axles, and our string kept getting stuck in the gears so it kept adding a lot of friction.
