Abraham Lincoln
Henry Leland, a former manager of

L-series cars in 1922, was forced into bankruptcy and sold for
US$8,000,000 to the Ford Motor Company on February 4, 1922,
which went to pay off some of the creditors.

11. Question 5
What is the device that allows a cars
driving wheels to turn at different
speeds when cornering?

12. Answer 5
Differential
A differential is a particular type of simple planetary
gear train that has the property that the angular
velocity of its carrier is the average of the angular
velocities of its sun and annular gears. This is
accomplished by packaging the gear train so it has a
fixed carrier train ratio R = -1, which means the gears
corresponding to the sun and annular gears are the
same size. This can be done by engaging the planet
gears of two identical and coaxial epicyclic gear
trains to form a spur gear differential. Another
approach is to use bevel gears for the sun and annular
gears and a bevel gear as the planet, which is known
as a bevel gear differential.
