1. The drums were connected via a differential gear to twin contra-rotating propellers. 2. This design would have been simpler than using a differential gear . 3. Lacking this extra gear meant that reverse was done with a differential gear . 4. The tow vehicle will still move the weight regardless of the differential gear ratio. 5. They steered through an unusual wet band brake system through a differential gear system. 6. The rear differential gear ratio was changed to 3.31 : 1 for both transmissions. 7. The new transmission was joined by a 3.73 : 1 rear differential gear ratio. 8. The hypothesis that there were south-pointing chariots with differential gears originated in the 20th Century. 9. A differential gear train can be used to allow a difference between two input axles. 10. It requires a differential gear , a gearing arrangement that sums or differences two angular inputs.
