What are some interesting facts about levers?

In: Kinematics [Edit categories]

Answer:

Answer

I always found it interesting that there are three classes of levers:

1st class: The exerted force (Fe) is on the opposite side of the fulcrum (F)of the resulting force (Fr). For example, a pry bar.
Fe-----F-----Fr

2nd class: For example, a wheelbarrow:
F-----Fr-----Fe
(the fulcrum is the wheel)

3rd class: For example a baseball bat
Fr-----Fe-----F
(the fulcrum is your hand)

A fingernail clipper is a compound lever. It has a 2nd class and a 3rd class.
