How can you lift very heavy objects without using powerful machinery?

 

               For thousands of years people have used levers as a way of transferring a force from one place to another, and to change the amount of movement that results.

               To move a heavy object, a long lever can help. The lever is free to move about a point called the fulcrum. The shorter end of the lever is placed under the object, and force is applied to the longer end. This will cause the object to be lifted, but the long end of the lever will have to be pushed down a long way to lift the object only a short distance. With a long-enough lever you could lift a car for a short distance.
