FCTC TEST PREP EVALUATION FULL
SOLUTION UPDATED STUDY GUIDE
⩥ 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.
⩥ 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.
⩥ 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
⩥ 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
⩥ 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
⩥ Formula for Determining the head pressure difference between an
intake and output.
Answer: 1 vertical foot = 0.433 psi
1 psi = 2.31 vertical feet
⩥ 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, 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?.
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.
⩥ Recall and Comprehend Technical Information.
Answer: - Read one to four essays
-35 questions total (including questions for essays in back of the test
booklet)
- notes can be written on the essay packet, NOT any other testing
material.
- 15 - 20 questions from these essays were handed out in the first 30
minutes.
⩥ Gear Train, or commonly called "Transmission".
Answer: Two or more gears working in a sequence, producing
mechanical advantage through a gear ratio.
⩥ Relationship between Speed, Torque, and Power:.
Answer: Power = 2pi x Speed (w) x Torque (nm)/ 60
