A family of pololu motors have speed reduction gear trains that range from 1:1 to 400:1 (link to general catalog). Answer the following questions below. a. For a specific gear train

the gear set includes the following teeth numbers 12, 10, 10, 22, 22, 24. The layout is shown below with red stars indicating the meshing locations. Determine the overall gear ratio (output speed/ input speed). Tip: use the tooth velocity method described in lecture. 22 10 24 Note that the 2 middle gears are compound gears where the inner gear and outer gears are rigidly attached and thus rotate at the same angular velocity. Compound Gear b. What is the product number of the low-power motor that corresponds to the gear train?
