The fulcrum point decides how much mechanical advantage you get.
In a see/saw the point is in the center, each side is equal.
If you move that so one side is 6 foot long, and the other 2 foot long, the longer side has a 3:1 advantage over the shorter side. It can lift the same weight with 1/3rd the effort.
The problem lies in the trade off. The longer side has to move a long distance but lifts heavier loads.
The shorter side moves a small amount to move the other side a long distance, but requires a great deal of effort.
Like most things in science, you trade effort, for volume of movement

Third class levers have the force between the fulcrum and the resistance?
Yes.
Can a lever have more than one fulcrum?
Yes, you can stack levers, however each fulcrum is independent in the plane for which it functions.
Class levers have the resistance force between the effort force and the fulcrum?
Class 2.
What is the fulcrum called at the end with the load in the middle?
The fulcrum can only ever be called the fulcrum. You may be asking about the three classes of levers: if so, you need to ask the question with enough description to allow an answer.
What are some class 1 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 .
Levers can be divided into classes depending on the position of the?
on the position of 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.
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.
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.
What is a sentence that describes the way levers are classified?
Levers are classified based on the relative positions of the fulcrum, effort, and load.
Basis for the classification of lever?
The classification of levers is based on the relative positions of the effort, load, and fulcrum. There are three types of levers: first-class levers have the fulcrum placed between the effort and load, second-class levers have the load between the fulcrum and effort, and third-class levers have the effort between the fulcrum and load.
How are levers divided?
Levers are divided into three classes based on the relative positions of the input force, the fulcrum, and the output force. Class 1 levers have the fulcrum positioned between the input and output forces, class 2 levers have the output force between the input force and the fulcrum, and class 3 levers have the input force between the fulcrum and the output force.
What are Second and third class levers differentiated by?
Second class levers have the load between the fulcrum and the effort (load-fulcrum-effort), while third class levers have the effort between the load and the fulcrum (load-effort-fulcrum). Second class levers provide mechanical advantage and are more efficient for lifting heavy loads, while third class levers provide a speed advantage but require more effort.
All levers have a rigid arm that turns around a point called the what?
Fulcrum
How are levers classified?
levers are classified by the locations of the input and output forces relatively to the fulcrum
How do levers work?
levers work by having a effort that lifts a load, and a fulcrum balances the two
In a living lever in your body what acts as the levers fulcrum?
The joint, near where the tendon is attached to the bone, acts as the fulcrum.
