In a mechanical setup, if the load operates between the fulcrum and the force applied, what type of lever is being used?

First class lever

Second class lever

In this scenario, when the load is positioned between the fulcrum and the force applied, the lever in question is classified as a second class lever.

Second class levers are characterized by the arrangement where the load is situated between the effort (force applied) and the fulcrum. This configuration allows for the load to be moved with less effort compared to first class levers, where the force and load are on opposite sides of the fulcrum, or third class levers, where the effort is applied between the load and the fulcrum.

The unique positioning in a second class lever leads to an increase in mechanical advantage, enabling the force applied to lift heavier loads with greater ease. This principle can be commonly observed in scenarios such as a wheelbarrow, where the load is placed between the wheel (fulcrum) and the handles (force applied), exemplifying the efficiency of a second class lever system.
