In 1877, a patent for a(n) ________ carriage with a one-cylinder engine
was obtained by George Seldon. - ANSWER ✔✔FWD
In a front engine, rear-wheel drive vehicle, the transmission sends power
to the final drive assembly, which then changes the direction of the
twisting force ____ degrees so it can be sent out the axles to the wheels
and tires. - ANSWER ✔✔90
Technician A says synchronizers are used to match the clutch and input
shaft speeds to provide easier gear changes. Technician B says a
,synchronizer matches gear speed with shaft speed. Who is correct? -
ANSWER ✔✔B
Technician A states that early cars with one-cylinder engine had one
belt-driven high gear for speed and one belt-driven low gear for
increased torque. Technician B states that if the car needed to climb a
hill, the driver had to stop, get out, and change the belt to the lower gear.
Who is correct? - ANSWER ✔✔Both
This early engine had one belt-driven high gear for speed, and one belt-
driven low gear for increased torque: - ANSWER ✔✔The front-wheel
drive carriage with a one-cylinder engine
Mechanical advantage can be used to generate a larger output force,
but it requires a(n): - ANSWER ✔✔increase in input distance and
speed.
Technician A says gear ratios can be found by comparing the number of
teeth on the drive gear to those on the driven gear. Technician B says
gears with the same number of teeth have a ratio of 2:1. Who is correct?
- ANSWER ✔✔A
All gear ratios are calculated by the formula: - ANSWER ✔✔driven
gear divided by the drive gear.
,Because of the _______, the transmission/transaxle has multiple paths
along which the power can flow. - ANSWER ✔✔Various gear sets
When tracing the power flow from the engine to the drive wheels, what
transmits power directly to the transmission input shaft? - ANSWER
✔✔Clutch assembly
As transmission gear ratios are changed, output torque and output
speed also change. If output speed is increased, output torque: -
ANSWER ✔✔is decreased
The manual transmission receives power from the engine by way of the:
- ANSWER ✔✔clutch assembly.
The purpose of the clutch safety switch is to: - ANSWER ✔✔allow the
engine to be cranked only when the clutch pedal is depressed.
In a vehicle equipped with a manual transmission, once a gear is
selected, the driver slowly releases the clutch pedal and progressively
connects the ________ to the transmission. - ANSWER ✔✔engine
Which of the following is affected by the gear ratio of the final drive
assembly? - ANSWER ✔✔Both

the rotational speed of the axles. Technician B says that the final drive is
used to provide an increase of twisting force to the axles. Who is
correct? - ANSWER ✔✔B
All of the following are used by auto manufacturers when selecting the
final drive gear ratio, EXCEPT: - ANSWER ✔✔the suspension's
standing height.
