What is the major factor controlling how levers work?
A) the structural characteristics of the muscles of the person using the lever
B) the weight of the load
C) the difference in the positioning of the effort, load, and fulcrum
D) the direction the load is being moved

Question

Quizplus · Accepted Answer

The positioning of the effort, load, and fulcrum determines the mechanical advantage of the lever, which is the factor controlling how levers work. The mechanical advantage is calculated by dividing the distance from the fulcrum to the effort by the distance from the fulcrum to the load. Different positions of the effort, load, and fulcrum can result in different mechanical advantages and can make a lever more or less effective at moving a load.
