Classes of Levers - Correct Answer-Class 1, Class 2, Class 3 Class 1 Levers - Correct 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 - Correct 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 - Correct 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 - Correct 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? - Correct 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 - Correct Answer-1 vertical foot = 0.433 psi 1 psi = 2.31 vertical feet Overall Test Overview: - Correct Answer-1) 30-minute period to read 2 essays- 2 - hour time limit begins to answer (100 questions).
- Watch 2 short videos and answer (20 questions) based on the scenarios.
- Apply mechanical reasoning (25 questions, i.e. Fluid Dynamics, levers, belt and pulleys, gears)

Belt and Pulley Systems - Correct 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. What is a pulley (also called a "sheave" or "drum") - Correct Answer-A pulley is a wheel on an axle or shaft that is designed to support movement and change in direction of a belt or cable along its circumference. For a Rope and Pulley System that is a Block and Tackle, is characterized by: - Correct Answer-* If the rope does not dissipate or store energy, then its mechanical advantage is the number of parts of the rope that act on the load.- if the anchor knot is at the load ("A", "D", and "E") then the mechanical advantage will be odd. (1:1, 3:1, 5:1, etc.)- if the anchor knot is at the anchor ("B", "C") then the mechanical advantage will be even. (2:1, 4:1, 6:1, etc.)- to calculate haul distance, multiply the distance need to go by the mechanical advantage.
