Some Class-I levers, and all Class-III levers.
Well Levers are a simple machine that was created by someone special. Levers help us make work easier. GO LEVERS!!!! Well Levers are a simple machine that was created by someone special. Levers help us make work easier. GO LEVERS!!!!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-----Fr2nd class: For example, a wheelbarrow:F-----Fr-----Fe(the fulcrum is the wheel)3rd class: For example a baseball batFr-----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
Yes.
Lever belongs to the category of simple machines. They are three types of levers 1. First class levers 2. Second class levers 3. Third class levers In the first class levers fulcrum is in between applied force and load. common examples are Crowbar , Pair of scissors , SeeSaw , Skull and neck in our body .
Because of the lever's mechanical advantage.
Some Class-I levers, and all Class-III levers.
First Class Levers The fulcrum is between the input force and the load Always changes the direction of the input force and can be used to increase the force or the distance Second-class levers The load is between the fulcrum and the input force Does not change direction of the input force Output force is greater than the input force. Third-Class lever The input force is between the fulcrum and the load Does not change the direction of the input force Output force is less than input force.

Yes.
Class 2.
First class levers change direction of force applied, like using a crow bar to open a door.In a first class lever, the fulcrum is between the force arm and the resistance arm. Seesaws, crowbars, and oars are first-class levers.

Because the output distance is always greaterthan the input distance,and the product of (force) x (distance) is nearly the same on both ends.

First levers always follow the order: Load fulcrum effort/force. The load is at one end of the lever and the force is applied at the other end. The fulcrum is somewhere in between the load and force. Scissors are examples of 1st class levers or when elevating one's head above one's chest.
