A crowbar is a Class 1 lever (fulcrum or pivot in the middle) The trick to remembering which type is which is: FRE 123. If F the fulcrum is in the middle it's Class 1, if the Resistance (or load is in the middle (a wheelbarrow) it's Class 2 and if the Effort is in the middle (tweezers) it's Class 3.
It's a class 1 lever because the curve part of the crowbar (the fulcrum) is in between the effort, at the end of the crowbar where your hands are, and the load side, the short side that pry's the thing open.

∙ 8y agoyes. A crowbar is a first class lever because the resistance is whatever it is prying, the effort is your pushing/pulling, and the fulcrum is somewhere in the middle....
