Choose the correct statement:

• The differential assembly does not allow the wheels on an axle to rotate at different speeds.

• Technically, "differential assembly" is the other name for "final drive assembly."

• The two varieties of differential assembly are open and closed.

• Without the differential assembly, the tires would bind, skip, hop, and slide when going around a corner.

If the driven gear (the output gear) has more teeth than the drive gear (the input gear), then the gear set will have mechanical advantage because the smaller drive gear has to rotate faster than the larger driven gear, giving an increase in output force.
