Sample Practice Test Questions

Electronics Information

Which of the following is the preferred method for splicing wires?

soldering

Splicing is permanently joining two wires together. Splicing can be done with screw-on connectors or wire crimps but the preferred method for splicing is soldering. Soldering takes the most effort but results in a connection that is electrically and mechanically identical to the original wire.

Word Knowledge
The accountant advised Justine not to report her incidental expenses.
petty
Minor.
Word Knowledge
Regurgitate most nearly means:
spew
To pour out or throw back.
Shop Information

Which of the following statements about drill bits is not true?

drill bits are primarily left-handed

Drill bits remove material to create holes. They come in a variety of sizes, maxing out at ¼" for woodworking and ½" for metalworking. The majority of drill bits are right-handed which means they cut while rotating in a clockwise direction.

Automotive Information

Too much air results in a __________ air-fuel mixture that burns more slowly and hotter.

lean

The stoichiometric ratio defines the proper ratio of air to fuel necessary so that an engine burns all fuel with no excess air. For gasoline fuel, the stoichiometric ratio is about 14.7:1 or for every one gram of fuel, 14.7 grams of air are required. Too much air results in a lean air-fuel mixture that burns more slowly and hotter while too much fuel results in a rich mixture that burns quicker and cooler.

Word Knowledge
The longer Jorge waited in line at the ticket counter, the more his exasperation grew.
irritation
The state of being irritated.
Math Knowledge

Solve for z:
z2 + 6z - 13 = -z + 5

2 or -9

The first step to solve a quadratic expression that's not set to zero is to solve the equation so that it is set to zero:

z2 + 6z - 13 = -z + 5
z2 + 6z - 13 - 5 = -z
z2 + 6z + z - 18 = 0
z2 + 7z - 18 = 0

Next, factor the quadratic equation:

z2 + 7z - 18 = 0
(z - 2)(z + 9) = 0

For this expression to be true, the left side of the expression must equal zero. Therefore, either (z - 2) or (z + 9) must equal zero:

If (z - 2) = 0, z must equal 2
If (z + 9) = 0, z must equal -9

So the solution is that z = 2 or -9

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

Automotive Information

The __________ converts pressure on the brake pedal to hydraulic pressure in the brake lines.

master cylinder

The master (brake) cylinder converts pressure on the brake pedal to hydraulic pressure in the brake lines.

Electronics Information

Which of the following statements about electrical resistance is true?

the more resistive the conductor is the slower electron flow will be

Resistance is opposition to the flow of current. As resistance increases, current decreases as resistance and current are inversely proportional.
