What class of lever is a hole punch?

Answer 1

If you have the fulcrum ( unmoveable pivot point) between your hand and the object you are prying, it is a 1st class. If the end of the pry bar is wedged into a fulcrum and you are trying to move something between the end of the bar and your hand, it is a 2nd class.

My class used a pry bar as " a classic example of a 1st class lever"....sometimes true, but very common to use it as a 2nd class as well ( e.g. moving an alternator, etc...)

Answer 2

Pliers are first class levers because the fulcrum is between the resistance and the effort

Answer 3

3rd class levers, because the effort is in the middle.
