The distance between the effort and the fulcrum is known as the effort arm. It determines the amount of force required to move an object when using a lever. A longer effort arm requires less force to move the object, while a shorter effort arm requires more force.
An effort arm is the part of a lever where the input force is applied. This force is used to overcome the resistance in order to move the load. The length of the effort arm influences the mechanical advantage of the lever system.
