Effort Force
Effort force explained in an easy to understand way:
Imagine trying to open a tightly sealed jar of pickles. Just like you apply a certain amount of twisting force to loosen the lid, an effort force is the force you apply to a simple machine to make it work. In both cases, the effort you exert – whether it's the twisting motion on the jar or the applied force on a lever – is necessary to overcome resistance and achieve the desired outcome, such as opening the jar or lifting a weight.
