Question: 1 / 400

In a second class lever, where is the load typically located?

At the fulcrum

At one end

In between the fulcrum and the effort

In a second class lever, the load is positioned between the fulcrum and the effort. This arrangement allows the effort applied to be amplified, making it easier to lift or move the load. In this type of lever, the fulcrum is at one end, while the effort is exerted on the other end. This configuration means that when a person applies force at one end, they can effectively lift heavier loads because the distance from the effort to the fulcrum is greater than the distance from the load to the fulcrum.

Understanding this structure is essential in mechanics as it illustrates the principle of mechanical advantage. For example, a common second class lever is a wheelbarrow, where the wheel acts as the fulcrum, the load is in the center (where the items are placed), and the person lifts the handles at the other end. Thus, the design optimizes the force exerted to move heavier objects more easily.
