You are using a steel crowbar to lift a big rock, with a smaller stone as a fulcrum at the center of the crowbar, but you are not quite able to lift the rock. what can you change about this setup to lift the rock? choose the correct answer and explanation. move the small stone (the fulcrum) farther from the large stone. this gives you a greater lever arm. move the small stone (the fulcrum) closer to the large stone. this gives you a lower lever arm. move the small stone (the fulcrum) farther from the large stone. this gives you a lower lever arm. move the small stone (the fulcrum) closer to the large stone. this gives you a greater lever arm.
