The Compound Machine has to lift a 500g weight with a force of 300g or less. The machine must contain 3 or more mechanisms, such as simple machine, gears, a pulley and belt, or a chain and sprocket.

formula(S) used
IMA= De/Dr
fe: AMA=Fr/Fe AMA= Fr/Fe E= AMA / IMA IMA= De/Dr
_IMA= De/Dr
AMA=Fr/Fe E=AMA / IMA |
substitute and solve
1cm/5cm=0.2cm
x/3g=0.6g 0.6g/3g=0.2g 0.2cm/0.2g=100% 1:1=100%
31.32cm/9cm=3.48cm
5g/3g=1.67g 47.99% _ |
Final design
This the design that my team and i came up with. As the gear moves up the inclined plane, the weight goes up also.
