When we arrived in lab, we assembled our gears into the Lego transmission housing. When we were assembling the gears, some gears were not meshing correctly, and some gears were placed incorrectly on the shafts. We have sent new .STL files for reprinting and we should have them done by Friday. We are unable to test what we have now because of the incorrect gear meshing. Once the new pieces are printed, all gears (1, 2, 3, 4) will be able to run correctly. We hope that first gear will have the most torque and that fourth gear will have the highest RPM.
Despite the conflicts between our gears and shafts, we still managed a way to perform some testing.
We measured the RPMs:
First gear: 36 RPMs
Second gear: 124 RPMs
Third gear: 440 RPMs
Fourth gear: 536 RPMs
We also measured the torque of first gear:
The maximum grams that could be lifted was 400 grams.
Using this information, the experimental ratios are very close to our theoretical ratios.
