Sample Practice Test Questions

Mechanical Comprehension
What's the mechanical advantage of a wedge that's 3 inches wide and 12 inches long?
4

The mechanical advantage (MA) of a wedge is its length divided by its thickness:

MA = \( \frac{l}{t} \) = \( \frac{12 in.}{3 in.} \) = 4

General Science

Cirrus clouds are thin, wispy clouds composed of ice crystals. At what elevation to cirrus clouds form?

high-altitude

Cirrus clouds are thin, wispy high-altitude clouds composed of ice crystals that originate from the freezing of supercooled water droplets. Cirrus clouds generally occur in fair weather and point in the direction of air movement at their elevation.

Shop Information

This includes their interactions with the lithosphere (the rigid outer part of the earth, consisting of the crust and upper mantle), hydrosphere (all surface water), and atmosphere (the envelope of gases surrounding the planet).

Automotive Information

The __________ splits engine power between the front and rear axles of four-wheel drive vehicles.

transfer case

The transfer case splits engine power between the front and rear axles of four-wheel drive vehicles.

Electronics Information

Why is an insulator a poor conductor of electricity?

an insulator has few free electrons

Insulators have valence shells that are more than half full of electrons and, as such, are tightly bound to the nucleus and difficult to move from one atom to another.

Math Knowledge
73°

If angle a = 68° and angle b = 39° what is the length of angle c?

73°

The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 68° - 39° = 73°

Automotive Information

How are the cylinders numbered in V-type engines?

cylinder numbering varies by manufacturer

In V-type engines the numbering sequence varies by manufacturer.

General Science

Elements in the Periodic Table of the Elements are ordered by which of the following?

atomic number

The Periodic Table of the Elements categorizes elements primarily by the number of protons in their nucleus (atomic number) and secondarily by the characteristics they exhibit.
