Sample Practice Test Questions

Word Knowledge
Manifest most nearly means:
evident
Obvious.
Automotive Information

The wheel __________ is the mounting point for the wheel and tire assembly.

hub

The wheel hub is the mounting point for the wheel and tire assembly. The wheel hub can rotate while being held stable by the steering knuckle which applies the motion of the control arms to the wheels.

Mechanical Comprehension
What is the power output of a 9 hp engine that's 85% efficient?
4207.5 \( \frac{ft⋅lb}{s} \)
\( Efficiency = \frac{Power_{out}}{Power_{in}} \times 100 \)
Solving for power out: \( P_{o} = \frac{E \times P_{i}}{100} \)
Knowing that 1 hp = 550 \( \frac{ft⋅lb}{s} \), Pi becomes 9 hp x 550 \( \frac{ft⋅lb}{s} \) = 4950 \( \frac{ft⋅lb}{s} \)
\( P_{o} = \frac{E \times P_{i}}{100} = \frac{85 \times 4950 \frac{ft⋅lb}{s}}{100} \) \( = \frac{420750 \frac{ft⋅lb}{s}}{100} \) = 4207.5 \( \frac{ft⋅lb}{s} \)
Word Knowledge
Accentuate most nearly means:
highlight
To emphasize.
Word Knowledge
Heidi's grandfather was gruff, barking stern orders and hardly smiling.
surly
Rough or stern in manner or speech.
Word Knowledge
The sweet cookie was a perfect foil to the sour lemon sorbet.
complement

To amuse.
Automotive Information

A __________ is designed to drive a pair of wheels while allowing them to rotate at different speeds.

differential

A differential is designed to drive a pair of wheels while allowing them to rotate at different speeds. A transaxle is a transmission that incorporates the differential in one package. Most front-wheel drive cars use a transaxle while rear-wheel drive cars use a transmission and separate differential connected via a drive shaft. The differential is incorporated into the drive axle which splits engine power delivered by the drive shaft between the two drive wheels. All-wheel drive cars typically use a transaxle that includes an output shaft to the rear differential.

General Science

During digestion, the kidneys filter substances from the blood. Which of the following is not filtered by the kidneys?

fats

Chemical waste like excess water, minerals, and salt are filtered from the blood by the kidneys and secreted into the urine. Urine is transported from the kidneys to the bladder through ureters.

Word Knowledge
Claudia's implausible excuse failed to convince her teacher.
improbable
Unbelievable.
