Want this question answered?
the position is that lever is near fulcrum exposed to the left sex of the effort which makes the effort to troposphere
First comes effort ,fulcrum and load
To lift the rock using the least amount of effort force,should push on the position farthest away from the fulcrum. This is position Z.
The length of the "effort arm" of the lever clearly has a great influence on the 'effort' the pusher must input to the lever in order to do the job. But in terms of the "work" done ... in the formal sense of Work as defined in Physics = (force) x (distance) ... the length of the effort arm should have no effect on the quantity of work.
Measure the distance from the fulcrum to 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.

On the lever
The length of the "effort arm" of the lever clearly has a great influence on the 'effort' the pusher must input to the lever in order to do the job. But in terms of the "work" done ... in the formal sense of Work as defined in Physics = (force) x (distance) ... the length of the effort arm should have no effect on the quantity of work.
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.

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.
Load = the force of the weight of the lever fulcrum = the point of which the lever rests effort = the force you apply to the lever
Load = the force of the weight of the lever fulcrum = the point of which the lever rests effort = the force you apply to the lever
The portion between the fulcrum and the effort applied in a lever is called effort arm.
