1.	A lever has an arm that rests and rotatesagainst this point.
Answer» Alever is a simple machinethat allows you to gain a mechanical advantage in moving an object or in applying a force to an object. It is considered a "pure" simple machine because friction is usually so small that it is not considered a factor to overcome, as in other simple machines. A lever consists of a rigid bar orbeam that is allowed to rotate or pivot about a fulcrum. An applied force is then used to move a load. There are three common types or classes of levers, depending on where the fulcrum and applied force is located
