FCTC Written w_video answers Questions with
CORRECT Answers (Grade A+)
Question 1:
Classes of Levers
Answer:
Class 1,
Class 2,
Class 3
Question 2:
Class 1 Levers
Answer:
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.
Question 3:
Class 2 Levers
Answer:
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.
Question 4:
Class 3 Levers
Answer:
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
,Question 5:
Lever Definitions
Answer:
Lever machine consisting of a beam or rigid rod pivoted at a fixed
hinged, or fulcrum.
Input Force = Effort
Output Force = Load or Resistance
Question 6:
What does "fre, 123"
mean?
Answer:
Fulcrum is in the middle for Class 1 LeversResistance (output) in
middle for Class 2Effort (input) in the middle for Class 3
Question 7:
Formula for Determining
the head pressure differ-
ence between an intake
and output
Answer:
1 vertical foot = 0.433 psi
1 psi = 2.31 vertical feet
Question 8:
Overall Test Overview:
Answer:
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, an-
gles, area, volume, decimals, ratios, percentages)
, 5) Recall and Comprehend Technical Information (35 questions, re-
call from first two essays, in addition to one or two more at this time)
Question 9:
Be mindful of questions
with absolutes. What are
some absolutes and why
watch out for them?
Answer:
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.
