3. What is a Differential? Key component of car
Last line of control from the gas pedal to the wheels
Controls the speed of wheels
Transmits power from engine to wheels

4. How it works? 3 primary tasks
Path of power = engine > drive shaft > input pinion > ring gear > axle shaft > wheels
Straight motion = gears within cage DO NOT rotate
Turning = gears within cage ROTATE

6. When and where are they needed?
Must be on all cars as they provide control
Front wheel drive = front axle shaft
Rear wheel drive = rear axle shaft
All wheel drive = one on each axle shaft and one on the center drive shaft

8. Conclusion
Integral part of a car
Located in all cars
3 primary tasks
