Lever Systems Flashcards
In a first-class lever system, where is the effort force, load force, and fulcrum located?
In a first-class lever system, the effort force and load are located on opposite sides of the fulcrum.
Give an example of a first-class lever system.
A seesaw is an example of a first-class lever system.
In a second-class lever system, where is the effort force, load force, and fulcrum located?
In a second-class lever system, the load force is between the effort force and the fulcrum.
