Quizplus · Accepted Answer

The positioning of the effort, load, and fulcrum is the major factor controlling how levers work. The relationship between the three determines the amount of force needed to move the load and the distance the load can be moved. The direction of the load, the structural characteristics of the muscles, and weight of the load are secondary factors that can influence the leverage, but the positioning of the effort, load, and fulcrum is the primary determinant of how the lever will function.
