The lever class is determined by where the effort is placed relative to the fulcrum and the load. In the arrangement where the effort acts between the fulcrum and the load, you have a Type III lever. This means the muscle or force you apply pulls on the lever from a point between the pivot and the object being moved. A common example is the forearm when the elbow acts as the pivot and the hand carries a load: the biceps muscle attaches between the elbow joint and the hand, producing movement by pulling in that middle position. Because the effort is between the fulcrum and the load, this setup typically produces a greater speed and a larger range of motion but less force amplification (mechanical advantage) compared with the other lever types. The other configurations place the fulcrum between effort and load, or the load between fulcrum and effort, which are not the described arrangement.
