Hi, I'm taking an Advanced Competitive Science class, and we are asked to build gear trains with certain gear ratios using Lego gears.
I am trying to make a 4.25:1 gear ratio with four gears only.
The different types of gears are the 8 tooth, the 16 tooth, 24 tooth, and the 40 tooth gear.
I've spent a long time trying to figure this one out, and I can't seem to figure this one out.
Maybe we have to use a different gear such as the worm gear or something?
Here is an example of a gear train made with two gears and a ratio of 5:1, a 40 tooth gear and an 8 tooth gear.
