lever-first+class

A first class lever has the fulcrum in between the effort and the load. A seesaw, a boat sweeping (type of rowing), and a pair of scissors are good examples of a first class lever is.



Scissors are a great example of a first class lever. The fulcrum is the screw in the middle. the load is the paper you cut at the end. The effort is the holes you put your hands through to cut.
