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.
A see-saw provides good fun. Although you might not think so your knives, forks and spoons are levers. You have the brake and gear change levers on a cycle. You might not be aware that there are three basic types of levers. Many switches are levers. Your own body has quite a few "bone" levers. When you flick a small ball of paper by using your ruler you are using a lever. You use a lever called a spoon to stir with. A bedroom door is a lever, as are most hinged things.
Increasing force by mechanical advantage.
>
Mechanical advantage = distance moved by input / distance moved by output
>
Output force = input force * mechanical advantage
>
Force * distance = work done
>
(Input) force * distance = (Output) force * distance
