What are the advantages of using a lever?

Levers are used to multiply force, In other words, using a lever gives you greater force or power than the effort you put in. In a lever, if the distance from the effort to the fulcrum is longer than the distance from the load to the fulcrum, this gives a greater mechanical advantage.

What are fun facts about levers?

Fun Facts

  • The longer the lever, the higher you can lift an object.
  • In a type 1 lever, the fulcrum (pivot) is between the object to be moved and the effort.
