Chapter 6 Chapter 6 Work and Power Work and Power Section 3 Notes on Levers ONLY
Levers A lever is a rigid bar that is free to turn about a fixed point. The fixed point about which a lever rotates is called the fulcrum. The input arm of a lever is the distance from the fulcrum to where the input is applied (usually by a person) The output arm of a lever is the distance from the fulcrum to where the output is exerted by the lever.
Locating the Positions on a Lever Fulcrum is the fixed point about which the lever rotates Load/Output Force is what the lever is lifting/moving Effort/Input Force is usually where you are applying the force.
The Three Classes of Levers There are three classes of levers depending on where the FULCRUM, EFFORT and LOAD are located on the lever or which of these positions located in the CENTER . Think, FLE 1st Class Lever 2nd Class Lever 3rd Class Lever FULCRUM is located in the center LOAD is located in the center EFFORT is located in the center
