In a lever system, the fulcrum is the point around which the lever pivots. When a person is lifting a boulder with a lever, the fulcrum would typically be positioned between the boulder (the load) and the point where the person applies force (the effort). Depending on the setup, the fulcrum could be a sturdy object or a fixed point on the ground beneath the lever. If you can visualize the setup, just identify the pivot point used to lift the boulder.
use the image of a person lifting a boulder with a lever to answer the question. Where is the fulcrum in this situation?
