Which lever class is described as having the load between the fulcrum and the effort?

• A. First class lever
• B. Second class lever
• C. Third class lever
• D. Wheelbarrow lever

Answer: (C)

When classifying levers, the arrangement of the fulcrum, load, and effort is what matters. If the load is positioned between the fulcrum and the effort, you’re describing a second-class lever. This setup gives a mechanical advantage: you can lift a heavier load with less effort, though you have to move the load a shorter distance. A wheelbarrow is the classic example: the wheel acts as the fulcrum, the load sits in the barrow between the wheel and your pushing effort at the handles. By contrast, if the effort is between the fulcrum and the load, that’s a third-class lever, like in many arm movements where the biceps apply force between the elbow and the hand, and the load sits farther out. So the described arrangement corresponds to a second-class lever, not the third-class arrangement.
