Sample Practice Test Questions

General Science

Which of the following substances gives up positively charged hydrogen ions (H+) when dissolved in water?

acid

An acid is a substance that gives up positively charged hydrogen ions (H+) when dissolved in water. A base (alkaline) gives up negatively charged hydroxide ions (OH-) when dissolved in water. pH is a scale that measures of how basic or acidic a solution is. Numbered from 0 to 14, solutions with a pH of 7 are neutral, less than 7 are acidic, more than 7 are alkaline.

General Science

Which of the following is not one of the outer planets?

Venus

In contrast to the solid terrestrial planets, the outer planets (Jupiter, Saturn, Uranus, and Neptune) consist of hydrogen and helium gas and water.

Math Knowledge
24

If a = c = 3, b = d = 8, and the blue angle = 58°, what is the area of this parallelogram?

24

The area of a parallelogram is equal to its length x width:

a = l x w
a = a x b
a = 3 x 8
a = 24

Shop Information

Which type of screwdriver has a x-shaped indentation on the head?

phillips

Screwdrivers come in many different handle, shaft, and tip configurations for use in a wide variety of applications. Screwdrivers are classified by their tip which is shaped to fit a corresponding screw head. Common tips are slotted (flat) and Phillips (x-shaped).

Word Knowledge
The introduction to the complex novel was, thankfully, written in clear accessible language.
approachable
Easy to reach or to approach.
Automotive Information

__________ are made with wide gap coils of rigid steel cable and both hold the vehicle chassis up off the ground and absorb energy from wheel movement making for a smoother ride.

suspension springs

Suspension springs are made with wide gap coils of rigid steel cable and both hold the vehicle chassis up off the ground and absorb energy from wheel movement making for a smoother ride.

Shop Information

Which of the following is used in metal work for shaping metal?

ball peen hammer

Ball peen hammers are most commonly used in automotive repair. They have rounded heads and are used to drive punches and chisels.

Shop Information

Which of the following is not an advantage of using a tape measure over using a ruler?

measure with more accuracy

Rulers are used to both measure distance and to draw straight lines. Tape measures are flexible rulers useful for measuring longer distances and in tighter spaces. Rulers and tape measures provide similarly accurate measurements.

Mechanical Comprehension

The principle of moments defines equilibrium in terms of:

torque

According to the principle of moments, you can maintain equilibrium if the moments (forces) tending to clockwise rotation are equal to the moments tending to counterclockwise rotation. Another name for these moments of force is torque.

General Science

Which of the following does not represent the freezing point of water?

0°F

The Fahrenheit scale fixes the freezing point of water at 32°F, the Celsuis scale at 0°C, and the Kelvin scale at 273K.
