Firefighter Exam - Mechanical Aptitude
UPDATED ACTUAL Questions And
CORRECT Answers
Steel Ruler - CORRECT ANSWER - Has linear gradations to measure a workpiece. It can
double as a straightedge. (Average length is 12in.)
Steel Tape Measurer - CORRECT ANSWER - Has linear gradations (metric or English)
on a flexible metal tape. The tape automatically retracts into a small housing for convenience.
(Normal length is 3 to 19 feet.)
Wing-Up Tape Measure - CORRECT ANSWER - Has linear gradation (metric or English)
on a flexible metallic tape used to measure. The tape can be retracted into a circular housing by
the use of a small crank on one side of the housing. (Normal length is 30 to 100 feet.)
Micrometer Calipers - CORRECT ANSWER - Used in determining precise
measurements. Can measure from 1 to 300 millimeters, depending on the tape selected.
Vernier Calipers - CORRECT ANSWER - Used in determining precise internal or external
measurements. Measuring capacity is 6 yo 72 inches or 150 to 1800 millimeters.
Side Calipers - CORRECT ANSWER - Use is comparable to the vernier calipers;
however, the gradations are not precise. Its measuring capacity is up to 3 inches.
Outside Calipers (Bow Calipers) - CORRECT ANSWER - Used to transfer external
measurements from a rule, or to match two items to fit. Measuring capacity is up to 3 inches.
Inside Calipers - CORRECT ANSWER - Used to transfer internal measurements from a
ruler, or to match two items to fit.
, Spring Dividers (Bow Compass) - CORRECT ANSWER - Used to inscribe circles or arcs
or to calibrate equal divisions on a line.
Depth Gauge - CORRECT ANSWER - Used to determine depths of holes, grooves, and
mortices.
Screw Pitch Gauge - CORRECT ANSWER - Used to determine the pitch of a machined
thread. Each blade is calibrated in metric units.
Carpenter's Steel Square (Framing Square) - CORRECT ANSWER - Used to check the
squareness of framing (i.e., 90-degree or right angles). There are metric or English-system
gradations for measuring as well.
Combination Square - CORRECT ANSWER - An all-purpose tool that can measure and
serve as a try square, miter square, and level. Measuring capacity in metric or English gradations
is 12 inches.
Try Square - CORRECT ANSWER - Used to determine if a workpiece is square (i.e., has
90-degree right angles).
Protractor - CORRECT ANSWER - Used as an instrument to draw or plot angles (0 to 180
degrees) on a surface.
T-Bevel - CORRECT ANSWER - Used to mark or verify angles on a workpiece.
Normally a protractor is used to serve a point of reference.
Level - CORRECT ANSWER - Used to determine a true horizontal line or accurate level
of a surface.
Plumb Bob - CORRECT ANSWER - Used to determine a true vertical line.
