Sample Practice Test Questions

Mechanical Comprehension

Two or more pulleys used together are called:

block and tackle

Two or more pulleys used together constitute a block and tackle which, unlike a fixed pulley, does impart mechanical advantage as a function of the number of pulleys that make up the arrangement.  So, for example, a block and tackle with three pulleys would have a mechanical advantage of three.

General Science

Which of the following states of matter exists at the lowest temperature?

solid

Solids exist at a lower temperature than liquids which exist at a lower temperature than gases.

Arithmetic Reasoning

What is the greatest common factor of 52 and 36?

4

The factors of 52 are [1, 2, 4, 13, 26, 52] and the factors of 36 are [1, 2, 3, 4, 6, 9, 12, 18, 36]. They share 3 factors [1, 2, 4] making 4 the greatest factor 52 and 36 have in common.

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.

Word Knowledge

Overwhelmingly emotional.
General Science

Which of the following is not a base unit in the metric system?

degree Fahrenheit

The Fahrenheit scale is used for measuring temperature in the British system. The metric system uses the Celsius scale.

Electronics Information

General current flow in a transistor is from __________ to __________.

collector, emitter

The transistor is the foundation of modern electronic devices. It is made entirely from semiconductor material (making it a solid state device) and can serve many different functions in a circuit including acting as a switch, amplifier, or current regulator. A transistor works by allowing a small amount of current applied at the base to control general current flow from collector to emitter through the transistor.

General Science

The connective tissue that connects bones to other bones at joints is called:

ligaments

Tough fibrous cords of connective tissue called tendons connect muscles to the skeleton while another type of connective tissue called ligaments connect bones to other bones at joints (elbow, knee, fingers, spinal column).

Math Knowledge
30cm

If side x = 12cm, side y = 9cm, and side z = 9cm what is the perimeter of this triangle?

30cm

The perimeter of a triangle is the sum of the lengths of its sides:

p = x + y + z
p = 12cm + 9cm + 9cm = 30cm

Shop Information

When cutting hard metals with a hacksaw you should choose a blade with __________ teeth per inch (TPI).

high

Blades with more and smaller teeth (high TPI) cut harder metals more effectively while blades with fewer and larger teeth (low TPI) cut softer metals more effectively.
