Which lever type has the fulcrum located between the effort and the load?

• A. Second-class lever
• B. Third-class lever
• C. Fulcrum between the load and effort
• D. First-class lever

Answer: (D)

The main idea is how a lever is classified by the position of the fulcrum relative to where you apply force (effort) and what you’re moving (load). If the fulcrum sits between the effort and the load, you’re dealing with a first-class lever. This setup lets you pivot around the fulcrum and balance or magnify force depending on how far the effort arm and the load arm are from the fulcrum. Classic examples include a see-saw or a crowbar used to pry objects—the central pivot point is between where you push and where the load is.

In contrast, if the load sits between the fulcrum and the effort, you get a second-class lever, which provides a strong force advantage but moves the load more slowly. If the effort sits between the fulcrum and the load, you have a third-class lever, which favors speed and range of motion over force. So the lever type with the fulcrum between the effort and the load is the first-class lever.
