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
What are 1 class levers?
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 .
What is a sentence that describes the way levers are classified?
Levers are classified by where the fulcrum is located.
How do you lift heavy objects efficiently?

Which Daisy BB guns have plastic levers and which do not?
I think you are asking about the Daisy Red Ryder. The old ones had aluminum cocking levers. In 1947 Daisy stopped using metal levers because of WW!! and changed to aluminum until sometime in the mid 1950's. Plastic cocking levers on pre 1966 models had a warping problem.
What levers are in the human body?
When you bite using your front teeth is an example of a first class lever
What do first class levers do?
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.
What are the description of lever?
A lever is a simple machine that makes work easier for use; it involves moving a load around a pivot using a force. Many of our basic tools use levers, including scissors (2 class 1 levers), pliers (2 class 1 levers), hammer claws (a single class 2 lever), nut crackers (2 class 2 levers), and tongs (2 class 3 levers).
Do cars have levers?
yes They do have levers
Classification of 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.
Why are levers useful today?

What type of levers are on a bike?
Brake levers and gear levers. The pedals are also a sort of lever.
How many levers dose a mountain bike have?
Thre are several ways to interpret that question. If you're asking about things that are actually called levers, then the answer is probably 4 - one pair of shift levers and one pair of brake levers. Unless it's a gripshift equipped bike, in which case it'll only be one pair of brake levers. Or maybe it's a single-speed, in which case it also only has brake levers. Or maybe it's a fixie, which don't use shifters or brakes. Or its using rear gears only, giving it 3 levers. One shifter, two brakes. Or it's a rear gear gripshift - two brake levers. Or maybe you're asking about the mechanical definition of levers, in which case there's be a lot more. The handlebar is a lever, each crank is a lever, the wheels may be seen as levers. If you've got quick-release wheels and seatpost, those are levers too.
