The diagram below shows a lever with a stone fulcrum and a box. Josephine is trying to lift the box off the ground. Josephine placed the fulcrum between Point B and Point C and could not lift the box. What question should she ask to figure out where to place the fulcrum to minimize the amount of force she will need to use?
Should Josephine place the fulcrum at point C since it is between the fulcrum and the load, which will minimize the force needed to lift the box?
Should Josephine place the fulcrum at point D since it is closest to the load and furthest from the force applied, which will minimize the force needed to lift the box?
Should Josephine place the fulcrum at point B since it is further from the load and closer to the fulcrum, which will minimize the force needed to lift the box?
