Question:
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:
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:
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:
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:
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:
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
Question:
Overall Test Overview:.
Answer:
1) 30-minute period to read 2 essays- 2-hour time limit begins to answer (100
questions).
Question:
Watch 2 short videos and answer (20 questions) based on the scenarios.
Question:
Apply mechanical reasoning (25 questions, i.e. Fluid Dynamics, levers, belt and pulleys,
gears)
Question:
Mathematical Problems (20 questions, i.e. addition, division, angles, area, volume,
decimals, ratios, percentages)
Question:
Recall and Comprehend Technical Information (35 questions, recall from first two
essays, in addition to one or two more at this time)
, Question:
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.
Question:
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.
Question:
Gear Train, or commonly called "Transmission".
Answer:
Two or more gears working in a sequence, producing mechanical advantage through a
gear ratio.
Question:
Relationship between Speed, Torque, and Power:.
Answer:
Power = 2pi x Speed (w) x Torque (nm)/ 60 Torque = 60 x Power (kW)/2pi x Speed
(Rpm)
Question:
Belt and Pulley Systems.
Answer:
Two or more pulleys in common to a belt. If the pulleys are of differing pitch diameters,
a mechanical advantage is realized. Doesn't depend on ratio of teeth as with gears and
sprockets, only pitch diameter.
