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 >.<

∙ 13y agoIf you are using a ladder in its most common fashion i.e. propped against a wall.
The fulcrum is the point where the ladder meets the ground.
The load is the point where the person on the ladder is.
The effort is the point where the ladder meets the wall.

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.

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.

What is the difference between effort distance and load distance?

Is the fulcrum always located at the same place as the lever?
No, there are 3 types of load-fulcrum-effort systems and the fulcrum depends upon the effort and the load of the system...
Keeping the location of the effort constant Will the effort increase if the load is moved farther away from the fulcrum?
The magnitude of the effort is controlled by you, not by the distance of the load from the fulcrum. Moving the load farther away from the fulcrum has no effect on the effort. But if you want to leave the effort where it is and still lift the load with the lever, then you're going to have to increase the effort.
Where is fulcrum load and effort in fishing rod?
well the effort is in the middle as it is your hand moving while the fulcrum is your elbow and the rod is 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.
What are the 3 parts of a lever?
A Lever comprises of three components:Fulcrum or Pivot - the point about which the lever rotatesLoad or Resistance - the object that requires movingEffort - the force applied by the user of the lever system
What are the four parts of the lever?
load arm, effort arm, load, effort, fulcrum!
How much effort is required to lift the load if the load is 360N?
This will occur if the fulcrum is closer to the load than the effort.
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.
