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
Levers are simple machines that consist of a rigid bar (lever arm) that pivots on a fulcrum to help lift or move objects. There are three types of levers based on the relative positions of the effort, fulcrum, and load: first-class lever, second-class lever, and third-class lever. Levers are commonly used in everyday items like seesaws, crowbars, and scissors.
Some uncommon examples of third-class levers include tweezers, ice tongs, and some fishing rods. Third-class levers have the effort between the fulcrum and the load, increasing the speed and distance traveled by the load.
Examples of first-class levers include a seesaw, scissors, and a crowbar. In these levers, the fulcrum is located between the effort (force) and the load (resistance).
Some examples of first-class levers include a seesaw, scissors, and pliers. These levers have the fulcrum placed between the effort force and the load, allowing for a balanced distribution of force.
Some examples of levers that require pushing include: a seesaw, a crowbar, and a hand-held bottle opener.
No, not all levers have a mechanical advantage. The mechanical advantage of a lever depends on the specific positions of the effort, load, and fulcrum. Some levers may have a mechanical advantage of less than 1, resulting in a decrease in force but an increase in distance.
levers are used everywhere in the home it can balance things and you can hold some levers are boat pads bicycle brakes and seesaw plus an wheelbarrow

Yes. A bike will have several levers. The crank arms are levers, the brake levers are levers, the shifters are levers, the handle bar is a lever.

yes They do have levers
There are three different Classes of levers. Class One Levers have a fulcrum in the middle. Class Two Levers have a resistance in the middle. Class Three Levers have effort in the middle.
