FCTC CHEMISTRY AND FIRE SCIENCE
EXAMINATION TEST 2026 COMPLETE Q&A
WITH CORRECT SOLUTIONS
⫸ Class 1 Levers - Fulcrum is in the middle, with the effort (input)
force on one side of the fulcrum and resistance (output) on the other side
.Mechanical Advantage greater or less than 1
Ex: Seesaw, Crowbar, Pair of Scissors.
⫸ Class 2 Levers - Resistance is in the middle, the effort is applied on
one side of the resistance and the fulcrum on the other side
.Mechanical Advantage is always greater than 1
Ex: Wheelbarrow, nutcracker, bottle opener, or the brake pedal of a car.
⫸ Class 3 Levers - Effort in the middle, the resistance is on one side of
the effort and the fulcrum is located on the other side.
Mechanical Advantage is always less than 1
Ex: Pair of tweezers, human mandible
⫸ Lever Definitions - Lever machine consisting of a beam or rigid rod
pivoted at a fixed hinged, or fulcrum.
Input Force = Effort
Output Force = Load or Resistance
, ⫸ What does "fre, 123" mean? - Fulcrum is in the middle for Class 1
LeversResistance (output) in middle for Class 2Effort (input) in the
middle for Class 3
⫸ Formula for Determining the head pressure difference between an
intake and output - 1 vertical foot = 0.433 psi
1 psi = 2.31 vertical feet
⫸ Overall Test Overview: - 1) 30-minute period to read 2 essays- 2-hour
time limit begins to answer (100 questions).
2) Watch 2 short videos and answer (20 questions) based on the
scenarios.
3) Apply mechanical reasoning (25 questions, i.e. Fluid Dynamics,
levers, belt and pulleys, gears)
4) Mathematical Problems (20 questions, i.e. addition, division, angles,
area, volume, decimals, ratios, percentages)
5) Recall and Comprehend Technical Information (35 questions, recall
from first two essays, in addition to one or two more at this time)
⫸ Be mindful of questions with absolutes. What are some absolutes and
why watch out for them? - Examples of absolutes are "absolutely,
always, forever, completely, infinite, never, only, sole, undeniable, or
wholly".Absolutes or any sort of broad statements should be suspected
as wrong.
