Which lever class has the load between the fulcrum and the effort?

• A. Class 1 lever
• B. Class 2 lever
• C. Class 3 lever
• D. None

Answer: (B)

Understanding lever classes hinges on where the fulcrum, load, and applied effort sit relative to each other. When the load lies between the fulcrum and where you apply force, the lever arm from the fulcrum to the effort is longer than the arm from the fulcrum to the load. This gives a mechanical advantage: you can lift a heavier load with less effort, though you move the effort through a greater distance. A wheelbarrow is a classic example: the wheel acts as the fulcrum, the load sits between the fulcrum and your grip, and you lift at the handles.
