| 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.
