The function of a lever is used to move or lift objects.

That's called a tiller.

revel is the answer ... why do you ask? Working on an IQ test? ;)

On the side on which the force is being applied, the distance and force are directly proportional. On the other side of the lever, they are inversely proportional. If 1 pound of force is applied to a lever at 1 foot on the left side of the fulcrum, the lever will apply 1 pound of force 1 foot from the right side of the fulcrum. If 1 pound of force is applied 2 feet left of the fulcrum, the lever will apply 2 pounds of force 1 foot from the right side. If 1 pound is applied 4 feet left of the fulcrum, the lever will apply 4 pounds of force 1 foot to the right of the fulcrum. If 1 pound of force is applied 1 foot left of the fulcrum, at 2 feet on the right side, the force will be 1/2 pound. At four feet, it will be 1/4 pound. Etc,
