Which simple machine is like a humans arm?

A human arm is similar to a lever, which is one of the six simple machines. In this analogy, the elbow acts as the fulcrum, while the muscles provide the force to lift or move an object, similar to how effort is applied to one end of a lever to lift a load at the other end. The arm's ability to bend and extend allows it to perform various tasks, much like a lever can change the direction and magnitude of force applied.
