Sample Practice Test Questions

Math Knowledge
bisects

If the length of AB equals the length of BD, point B __________ this line segment.

bisects

A line segment is a portion of a line with a measurable length. The midpoint of a line segment is the point exactly halfway between the endpoints. The midpoint bisects (cuts in half) the line segment.

Mechanical Comprehension

An inclined plane increases ___________ to reduce ____________.

distance, force

An inclined plane is a simple machine that reduces the force needed to raise an object to a certain height. Work equals force x distance and, by increasing the distance that the object travels, an inclined plane reduces the force necessary to raise it to a particular height. In this case, the mechanical advantage is to make the task easier. An example of an inclined plane is a ramp.

Word Knowledge
Solace most nearly means:
comfort
Source of consolation.
Automotive Information

The fuel pressure regulator ensures that the fuel injectors receive fuel at a consistent and known rate. The fuel pressure regulator is part of the:

fuel rail

The electric fuel pump feeds pressurized fuel through a fuel filter to the fuel injectors via the fuel rail manifold. The fuel rail contains the fuel pressure regulator which ensures that the fuel injectors receive fuel at a consistent and known rate. Excess fuel bled off by the pressure regulator returns to the fuel tank through the fuel return line.

Automotive Information

Which of the following is the name for a transmission that incorporates the differential in one package?

transaxle

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.

Word Knowledge
Insinuate most nearly means:
imply
To suggest indirectly.
Word Knowledge
Turmoil most nearly means:
chaos
Extreme confusion, agitation.
Math Knowledge

A cylinder with a radius (r) and a height (h) has a surface area of:

2(π r2) + 2π rh

A cylinder is a solid figure with straight parallel sides and a circular or oval cross section with a radius (r) and a height (h). The volume of a cylinder is π r2h and the surface area is 2(π r2) + 2π rh.

Word Knowledge
Love–struck Charlie was oblivious to everyone but the object of his affection.
careless
Lacking awareness.
Electronics Information
DC source

This circuit component symbol represents a(n):

DC source

Direct current flows in only one direction in a circuit, from the negative terminal of the voltage source to the positive. A common source of direct current (DC) is a battery.
