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

A second-class lever is defined by having the load situated between the fulcrum and the applied effort. This configuration allows for a mechanical advantage, meaning that a smaller effort can be used to lift a larger load. Common examples of second-class levers include a wheelbarrow and a nutcracker.

In the context of a wheelbarrow, the wheel serves as the fulcrum, the load is placed in the bucket, and the effort is applied at the handles. This lever configuration allows the user to lift a heavy load with comparatively less effort, which is why it is classified as second class. Understanding how the placement of the load affects the mechanics of leverage is essential in identifying lever types accurately.
