Sample Practice Test Questions

Shop Information

Which of the following is the primary difference between pliers and pincers?

pliers squeeze, pincers cut or pull

Pincers provide a mechanical advantage that's used to cut, pinch or pull an object. The force applied to pincers is concentrated to a point or to an edge of the tool which allows pincers to be brought very close to a surface. Pincers are typically used for removing objects from a material to which they've previously been applied, for example, to pull nails from wood.

Automotive Information

Coolant is circulated through the engine by the:

water pump

The water pump is driven by a belt connected to the crankshaft and ensures that coolant moves through the engine and radiator.

General Science

Large, puffy, mid-altitude clouds with a flat base and a rounded top describe which of the following?

cumulus clouds

Cumulus clouds are large, puffy, mid-altitude clouds with a flat base and a rounded top. These clouds grow upward and can develop into a cumulonimbus or thunderstorm cloud.

Word Knowledge
Demeanor most nearly means:
disposition
Behavior towards others.
Electronics Information
Suppose you have 10 [6V 5A] batteries that you can connect together in series, in parallel, or in series-parallel. Which of the following voltage and ampere combinations cannot be attained using these 10 batteries?
60V 50A

Connecting the 10 batteries in series multiplies their voltage while keeping their current the same yielding a 60V 5A configuration. Connecting the 10 batteries in parallel multiplies their current while keeping their voltage the same yielding a 6V 50A configuration. Using a series-parallel connection, 5 batteries can be connected in series and 5 can be connected in parallel resulting in a 30V 25A configuration.

General Science

The gravitational interaction of Earth and the Moon is responsible for which of these?

tides

Tides are caused by the gravitational interaction of Earth and the Moon.

General Science

An electrically charged atom is a(n):

ion

A compound is a substance containing two or more different chemical elements bound together by a chemical bond. In ionic compounds, one atom borrows an electron from another atom resulting in two ions (electrically charged atoms) of opposite polarities that then become bonded electrostatically.

Automotive Information

The intake ports on the cylinder heads is fed outside air via the:

intake manifold

The intake manifold distributes outside air to the intake ports on the cylinder heads. The intake air filter removes any airborne contaminants before the air enters the engine.

General Science

Materials like metals that transfer heat efficiently are called:

conductors

Heat is always transferred from warmer to cooler environments and conduction is the simplest way this transfer can occur. It is accomplished through direct contact between materials and materials like metals that transfer heat efficiently are called conductors while those that conduct heat poorly, such as plastic, are called insulators.

Word Knowledge
Sarah thought George's ploy of borrowing her notes was a cowardly way to ask her out.
strategem
A contrived plan.
