twice as much weight can be lifted by applying a given force.
But, since work is force * distance, the effort must be applied through by moving twice the distance.
Think of a lever with the fulcrum 2 meters from one end, and 1 meter from the other. A 100N force can lift a 200N load, but that end of the lever must be moved twice as far. Same with block and tackle using pulleys.
