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.
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.
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
Fishing rods are considered third-class levers because the effort (force applied by the angler) is between the fulcrum (where the rod is held) and the load (the fish at the end of the line). This arrangement allows for greater speed and distance to be achieved when casting the line.
== == 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
Class-I . . . Effort and resistance on opposite sides of the fulcrum. Class-II . . . Both on the same side of the pivot, resistance closer to it. Class-III . . . Both on the same side of the pivot, effort closer to it.
The three types of levers are the 1st class, the 2nd class, and the 3rd class
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.
3rd class levers are in your arm.
1st class,2nd class and 3rd class
There was no 4th class, only 1st, 2nd, and 3rd.
1st class were 1,000 2nd class were 80 and 3rd class was 30
The passengers were grouped 1st class,2nd class and 3rd class.
It is a third class lever.
417 3rd class 456 2nd class 374 1st class.
1st Class: 833 2nd Class: 614 3rd Class: 1,006 Total: 2,453
There was no 4th class on the Titanic. Only 1st, 2nd and 3rd.
Your arm is a really good example
