In a second-class lever, the load is positioned where?

In a second-class lever, the load is positioned between the fulcrum and the effort arm. This arrangement allows for the application of effort to be more efficient in moving a greater load.

The design of a second-class lever enables the effort applied to create a mechanical advantage, meaning that you can lift heavier loads with less effort compared to other types of levers, such as the first-class lever where the fulcrum is in the middle. In practical terms, a common example of a second-class lever is a wheelbarrow. When using a wheelbarrow, the wheel acts as the fulcrum, the load is placed in the middle of the wheelbarrow, and the user applies effort at the handles, which are located at one end. This positioning of the load moves it closer to the fulcrum, which helps to reduce the amount of force needed to lift and transport the load, thereby showcasing the efficiency of a second-class lever.
