The effort of a lever is the force applied to one end.
The load is an object situated at the opposite end of the applied force.
The closer the force applied is to the point where the lever rotates, the higher the force needed. The amount of force necessary is also depends on the amount of mass and where that mass is. If there's more mass closer to the point of rotation, the easier it is to rotate.
It's why a racehorse's foot are thin and longer than other horse's feet for instance. The mass is concentrated from the knee upwards, and the foot is longer, giving it more speed for effort.

i think its a 1st class lever pivot between effort and load = 1st class load between effort and pivot = 2nd class effort between load and pivot = 3rd class
a lever
the difference between lever and pully is the you and me dont know that
Because a second class lever is a lever in which the resistance is located between the fulcrum and the effort. When you stand on your tiptoes, the fulcrum is located at your toes, the effort is at your Achilles tendon, and the resistance is the weight of your body pushing down. therefore, the resistance is between the fulcrum and the effort.

The lever class of a hammer depends upon its use. If the hammer is used as a claw to remove a nail, it is a first class lever. When the hammer is used to strike a nail, it is a third class lever. There are three classes of levers. The difference between the classes lies in the position of the load, the effort and the fulcrum. When the fulcrum is between the load and effort, the object is a first class lever. If the load is between the fulcrum and effort, the object is a second class lever. A third class lever places the effort between the load and the fulcrum.
3rd Class lever (Effort in Middle)
It depends on which type of lever you are using. If it is a Class II lever then the load is between the fulcrum and the effort.
it is a lever because it has the load,effort and the fulcrum
a lever
3rd Class lever (Effort in Middle)
3rd Class lever (Effort in Middle)

The portion between the fulcrum and the effort applied in a lever is called effort arm.
it is a lever because it has the effort, fulcrum and load official
