First class lever.
Fulcrum is between load and force.

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.
The examples of levers of second class are :--A bottle openerOrange squeezeretc.wheelbarrowdoornutcracker
first class lever
first class The point about which a lever rotates is called the fulcrum
The three types of levers are the 1st class, the 2nd class, and the 3rd class
In a second class lever, the fulcrum is located at one end, serving as the pivot point. The load is positioned between the fulcrum and the effort, with the effort applied on the opposite side of the fulcrum to lift the load. Examples of second class levers include wheelbarrows and bottle openers.
The mechanical advantage of a second class lever is always greater than 1. This type of lever has the load situated between the fulcrum and the effort, resulting in increased force output compared to the input force applied. Examples of second class levers include wheelbarrows and bottle openers.
All the levers in the world can be grouped in 3 classes, depending on how the effort point, the load point, and the fulcrum are lined up. Class I . . . fulcrum (pivot) is in the middle. Class II . . . load is in the middle. Class III . . . effort is in the middle. Each individual lever can only belong to one class.
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.
Class two levers provide a mechanical advantage by having the load situated between the fulcrum and the effort. This means that a smaller effort can be used to lift a larger load. Examples of class two levers include a wheelbarrow and a bottle opener.
Some examples of second-class levers include a wheelbarrow, a nutcracker, and a bottle opener. In these lever systems, the resistance is situated between the effort and the fulcrum, allowing for increased force to be exerted to overcome the resistance.
3rd class levers are in your arm.
Can openers are considered second-class levers because the load (the can) is positioned between the effort (the force applied by the user's hand) and the fulcrum (the pivot point of the can opener). This configuration allows for greater mechanical advantage, enabling the user to exert a smaller force to lift and puncture the can's lid. The design effectively amplifies the input force, making it easier to open cans.
Third class levers the Effort is between the Resistance and Fulcrum (FER) Examples are: · Mouse trap · Baseball bat · Tweezers · Nail clippers · Mandible · Hockey Stick · Fishing Rod · Door · Broom · Arm · Boat Paddle
The distinguishing characteristic of first-class levers is that the fulcrum lies between the effort force and the resistance force. Second-class levers have the resistance force between the fulcrum and the effort force. Third-class levers have the effort force between the fulcrum and the resistance force.
There are three basic types of levers: first-class, second-class, and third-class. These levers differ based on the placement of the fulcrum, effort, and load.
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.
