The advantage of a class 3 lever is that it decreases the amount of force that needs to be applied. In a class 3 lever, the effort is applied between the fulcrum and the load, which allows for a greater distance moved by the load compared to the effort applied. While it does not increase mechanical advantage like some other lever classes, it allows for a more efficient application of force over a greater distance.
