In a second-class lever, where is the load located relative to the effort and fulcrum?

In a second-class lever, the load sits between the fulcrum and the effort. This arrangement means the effort arm (distance from the fulcrum to where you apply force) is longer than the load arm (distance from the fulcrum to the load), giving a mechanical advantage greater than one. A wheelbarrow is a classic example: the wheel acts as the fulcrum, the load sits near the wheel, and you lift from the handles farther away. Because the load is between the fulcrum and your effort, you can lift more with less force.
