What is a key characteristic of a class 2 lever?

A key characteristic of a class 2 lever is that the load is positioned between the effort and the fulcrum. In this arrangement, the effort is applied on one end to lift the load located closer to the fulcrum, which enhances the lever's ability to lift heavier weights with less force. This configuration allows for greater mechanical advantage, making lifting more efficient.

In a class 2 lever, the distance from the fulcrum to the load is shorter than the distance from the fulcrum to the effort. This distance difference contributes to the ability of the lever to magnify the input force applied at the effort, which is effective for tasks such as lifting heavy objects with less effort.

The presence of the load closer to the fulcrum is what distinguishes class 2 levers from other lever types, adding to their unique mechanical benefits.
