Principally, a lever is a board, with some kind of object on one side that you want to move up, this it the load. and the effort is the force you exert either, down on the other side of the fulcrum, or up on the same side. there are three classes of levers, class 1 class 2 and class 3
class one, look at a seesaw, the fulcrum is the part holding it up in the middle, this is it's central balanceing point, weight of one person on one side will push down and make the other side go up, but if there are two people, the one that weighs more will go down because he has the most weight pressing down on his side.
class 2, imagine having the same seesaw, but noibody on it, now sombody stands on one side, and then walks closer to the fulcrum and stays there, if you hold the far end and puch up, you are exerting force on the same side of the fulcrum, but your pushing him up. if you can move the fulcrum farther away from the person your pushing up, it will take less effort to push him just as high.
class three, the seesaw has nobody on it, your friend steps onto one side of the farthest point, and you start pushing up from the same side of the fulcrum, but the different side of him, it's a class 2, but you are closer to the fulcrum then the weight, this is a class three.
examples:
class 1: seesaw (the way kids play on them)
class 2: I can't think of a good example.
class 3: catapult >.<

Relationship between position of fulcrum and effort required to lift load?
A relationship between two of it are when load come closer to fulcrum, you need more effort to use. But if load go far away from the fulcrum, you need less effort to use. A relationship between two of it are when load come closer to fulcrum, you need more effort to use. But if load go far away from the fulcrum, you need less effort to use.
What class lever is the mandible and where does the effort load and fulcrum go?
Third class: Fulcrum is the condyles, effort is the masseter muscle, and load is whatever you're chewing on.
Where are the load effort and fulcrum located on a second class lever?
No, the function of the fulcrum remains the same The only change would be the ratio of force to load The closer the fulcrum is the the load, the less force required to lift it The farther away the fulcrum is from the load, the more force required to lift it
How does the position of the fulcrum and the location of the load affect the amount of effort force you must exert to lift the load?
To do this you first have to calculate your ideal mechanical advantage (IMA). The IMA is equal to the effort distance (the distance from the fulcrum to where you will apply the effort) divided by the load distance (the distance from the fulcrum to the load). You can then set your IMA equal to your acutal mechanical advatage (AMA) which assumes 100% efficiency. The AMA is equal to the load force (the weight of what you are lifting) divided by the effort force (the # you are looking for). So, for example, if your IMA is 5 and your load force is 500 lbs: 5=500/effort force. Therefore the effort force would be 100 pounds.
Why is the can opener a second class lever?
because the load is situated between the effort and fulcrum
Where are the effort load and fulcrum locate in a first class lever?
The fulcrum is between the effort and the load.

A relationship between two of it are when load come closer to fulcrum, you need more effort to use. But if load go far away from the fulcrum, you need less effort to use.
What determines the class of a lever?
The class of a lever is determined by the relative positions of the fulcrum, load, and effort. In a first-class lever, the fulcrum is between the load and effort; in a second-class lever, the load is between the fulcrum and effort; in a third-class lever, the effort is between the fulcrum and load.
What is the relationship between the amount of effort required to lift the load and the distance the load is from the fulcrum?
The amount of effort required to lift a load is inversely proportional to the distance the load is from the fulcrum. This means that the closer the load is to the fulcrum, the more effort is needed to lift it, and vice versa when the load is farther from the fulcrum.
How are levers grouped?
Levers are grouped into three classes based on the relative position of the effort, load, and fulcrum. Class 1 levers have the effort and load on opposite sides of the fulcrum, Class 2 levers have the load between the effort and fulcrum, and Class 3 levers have the effort between the load and fulcrum.
Where are the effortloadand fulcrum located in a first class lever?
In a First Class lever, the fulcrum is between the effort and the load.
What two things does the location of the fulcrum and load affect?
The location of the fulcrum and load affects the amount of effort needed to lift the load and the distance the load can be moved. Placing the fulcrum closer to the load reduces the effort needed but limits how far the load can be moved, while placing the fulcrum closer to the effort increases the distance the load can be moved but requires more effort.
How are levers grouped into classes?
Levers are grouped into three classes based on the relative positions of the load, effort, and fulcrum. Class 1 levers have the fulcrum between the load and the effort. Class 2 levers have the load between the fulcrum and the effort. Class 3 levers have the effort between the fulcrum and the load.
First Second and Third class levers are determined by the location of what?
The location of the effort, load, and fulcrum determine if a lever is a first, second, or third-class lever. In a first-class lever, the fulcrum is between the effort and the load. In a second-class lever, the load is between the fulcrum and the effort. In a third-class lever, the effort is between the fulcrum and the load.
How do the three types of levers differ from one another?
The three types of levers differ based on the position of the load, effort, and fulcrum. In a first-class lever, the fulcrum is between the load and the effort. In a second-class lever, the load is between the fulcrum and the effort. In a third-class lever, the effort is between the fulcrum and the load.
Where is the effort load and fulcrum on a stapler?
The effort is the point on the back where the hand presses the stapler. The load is the staple. The fulcrum is the hinge at the back.
Where is the effort and fulcrum on a swing?
The fulcrum is the swing hinges and the effort is the seat, you sitting in it would be the load.
