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).
That's a tall order. I may need a lever to get up that high. For all the tools I will mention, some of them from a lever when you hold onto them and use them, others are levers in themselves. Let's have some fun, so here we go. First Class levers are like a teeter-totter or see-saw, a pair of scissors - which is two 1st class levers together, but I'll count as just one. There is also one in your elbow, one in your ankle, and another one in your jaw. That makes five. Second Class levers can be found in wheelbarrows, nutcrackers, your jaw and ankle, and vise grips; that's five again. Let's make it six with a canoe paddle, it's also a second class lever when you paddle with it in water. The last one is the easiest: Third Class levers can be found in lots more places, they are much more common. Here's a short, but diverse list: broom, fishing pole, hammer, your knee, pen, pencil, the joints in your fingers and toes not counting the first knuckle, a tennis racket, oh shucks just about every sporting device that you swing is a 3rd class lever when in use. The gas peddle in your car. Chopsticks, wooden spoons, fork, knife, spoon, toothbrush. And there are a whole lot more of all three.
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.
== == There are 3 class levers, 1st, 2nd and 3rd. A 1st class lever is a lever with its Fulcrum in between the Effort and the Load. An example is the scissors and a roller coasters and glow sticks.....!!!!! (JUST REMEMBER FLE 123 1= fulcrum in the middle 2=Load in the middle 3=Effort)A Class-I lever is a lever set up like a see-saw ... with the effort andthe load located at opposite ends, and the pivot between them.Class-II and Class-III levers both have the pivot at one end.Class-II . . . the effort is at the other end, and the load is in the middle.Class-III . . . the load is at the other end, and the effort is in the middle.A see saws is the easiest description of a 1st class lever. The fulcrum is in the middle and the force is applied on one side. Scissors and pliers are other 1st class levers.Examples of first class levers are-see saw-trebuchet-scissors-spud bar-chop sticksa form of lever in which the input and output forces are on either side of the fulcrumscissors ,beam balance , seesaw,oars
Levers can be all of them. A first class lever is when the pivot (funcrum) is in the middle. A second class lever has the load (resistance) in the middle, and the third class lever has the effort (force) in the middle. For example, a see-saw is a first class lever because the fulcrum is the in middle. A exmaple for a second class lever would be a can opener because the load, the can, is in the middle. And last, the thrid class lever is a arm because the effort is in the middle, because your elbow gives the effort to move the arm.
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

The three types of levers are the 1st class, the 2nd class, and the 3rd class
A scissor jack would be a series of 1st class levers.

Opening a tin of paint with a spoon is an example of a simple machine called a first class lever. There are three different types of levers, which are first class, second class, and third class levers.
you have lots of lever in your house, like a light switch, or a mouse trap! it all depends on if you need 1st 2nd or 3rd class levers.
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.
There are 3 basic types of levers. 1st class, 2nd class and 3rd class. some change the direction of the force, some do not. some increase the force, some do not. A broom is an example of increasing speed, but not force. The direction of the effort (force you put in) and the resistance (force applied to the floor) is the same.

1st class levers are levers which have fulcrum between the load and effort.1st class lever in our body is our elbow joint .fulcrum:elboweffort:bicepsload:armarm and head
