Описание: In this activity we see that lifting a scale by one of its ends requires more effort than lifting it by its centre. In the first case the load is completely on one side of the fulcrum while in the second case the load is distributed evenly on either side of the fulcrum. This change in load distribution allows us the exert less effort in the second case.
