A fulcrum lever is a simple machine that falls under the category of class 1 levers. In a class 1 lever, the fulcrum is positioned between the effort and the load, allowing for changes in the direction or magnitude of a force. Examples of class 1 levers in everyday life include scissors and seesaws.
Usually it is a first class lever, though it depends entirely on the specific application. What I first think of when someone tells me to "bring me that lever over here" is a spud bar or crowbar, which are used with the fulcrum between force and load. But if a wheelbarrow would be more appropriate, that person would be asking for a second class lever, or if a stapler is more appropriate to the situation then they would be asking for a third class lever. The following link has a much better discourse on levers than I can do.

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.
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.
Where are the effortloadand fulcrum located in a first class lever?
In a first-class lever, the effort is applied on one side of the fulcrum, and the load is on the opposite side of the fulcrum. The fulcrum is located between the effort and the load.
Is a screwdriver an example of a third class lever?
No, a screwdriver is an example of a first-class lever where the fulcrum is in the middle. In a third-class lever, the effort is between the fulcrum and the load.
What class of lever are ice tongs?
Ice tongs are a class 3 lever because the effort is between the fulcrum and the load.
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.
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.
Where are the effortloadand fulcrum located in a first class lever?
In a first-class lever, the effort is applied on one side of the fulcrum, and the load is on the opposite side of the fulcrum. The fulcrum is located between the effort and the load.
Is a screwdriver an example of a third class lever?
No, a screwdriver is an example of a first-class lever where the fulcrum is in the middle. In a third-class lever, the effort is between the fulcrum and the load.
How efficient is a lever?
That depends where the fulcrum is. The closer the fulcrum is to the load (one-class lever), the easier.
What class of lever are ice tongs?
Ice tongs are a class 3 lever because the effort is between the fulcrum and the load.
What is the difference between a 1st- 2nd- and 3rd-class lever?
The main difference lies in the position of the effort, load, and fulcrum in relation to each other. 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.
Do second and third class levers both have the fulcrum between the effort and the load?
No, in a second-class lever, the load is between the fulcrum and the effort, while in a third-class lever, the effort is between the fulcrum and the load.
What class lever is a seesaw?
A see-saw is a fulcrum type of lever.
Identify the class of lever for which the fulcrum is between the input force and the output force?
The class of lever where the fulcrum is between the input force and the output force is a class 1 lever. In this type of lever, the load is on one side of the fulcrum, while the effort (input force) is applied on the other side. An example of a class 1 lever is a seesaw.
What class of lever are scissors?
First Class LeverIt is a First class lever.
How are second and first class levers differentiated?
In a first-class lever, the fulcrum is located between the applied force and the load. In a second-class lever, the load is between the fulcrum and the applied force. Examples of first-class levers include a seesaw or scissors, while examples of second-class levers include a wheelbarrow or nutcracker.
