When considering a third-class lever, what is true about the position of the effort?

In a third-class lever, the effort is positioned between the fulcrum and the load. This configuration means that the effort force is applied closer to the fulcrum compared to the load. The classic example of a third-class lever is the forearm when lifting a weight in the hand; the elbow acts as the fulcrum, the effort is applied by the biceps muscle closer to the elbow, and the load is at the hand. This arrangement allows for a greater range of motion of the load compared to the effort applied, making it easier and more efficient to lift or move loads.

In summary, the statement indicating that the effort is at one end with the load in the middle accurately reflects the positioning in a third-class lever system, allowing for the proper understanding of how these levers function.
