  1. Vocabulary List • Lever • Fulcrum • 1st Class Lever • 2nd Class Lever • 3rd Class Lever

  2. Lever 1st Class Fulcrum 2nd Class 3rd Class

  3. Levers Lever: A rigid bar that is free to pivot, or _______, on a fixed point. Fulcrum: The _________ point that a lever pivots around.

  4. 1st Class Lever • Give 2 characteristics - ________ is in the middle. - Changes the _________of the input force.

  5. 2nd Class Lever • Give 2 characteristics - The ________ is in the middle. - Increase the ______.

  6. 3rd Class Lever • Give 2 characteristics - _________ is in the middle. - Increase the ___________.

  7. - Simple Machines Levers • Levers are classified according to the location of the fulcrum relative to the input and output forces.

  8. Mechanical Advantage • Find the distance from Fulcrum to Input Force * Example = 4 meters • Find the distance from Fulcrum to Output Force * Example = 1 meter C) Take A divided by B * 4 m ÷ 1 m = 4
