A second class lever is defined by the position of the resistance force, applied force, and fulcrum. In a second class lever, the resistance force is positioned between the applied force and the fulcrum. This configuration allows the lever to amplify the applied force, enabling a smaller effort to move a greater load.

For example, when using a wheelbarrow, the wheel acts as the fulcrum, the load (resistance) is placed in the wheelbarrow's tray, and the person lifting the handles applies the force at one end. The key characteristic of a second class lever is that both the applied force and resistance force are on the same side of the fulcrum, allowing the load to be lifted efficiently. This positional arrangement distinguishes second class levers from first and third class levers, each of which has a different setup related to the arrangement of forces and the fulcrum.
