This diagram shows the relative position of the fulcrum in the three basic types of levers, with arrows indicating the direction of the effort and the downward force of the load.
top: The effort and load are on opposite sides of the fulcrum, as in a crowbar.
middle: The load is between the fulcrum and effort, as in a wheelbarrow.
bottom: The effort is between the fulcrum and load, as in a person's forearm, where the fulcrum is the elbow and the load is something held in the hand.
