A person uses a screwdriver as a lever to open a can of paint. Where is the fulcrum in this situation?
3 answers
The fulcrum in this situation is the tip of the screwdriver that is inserted into the lid of the can of paint.
so where the end of the screw driver lifts up the lid of the can?
Yes, that's correct. The end of the screwdriver lifts up the lid of the can, while the fulcrum (the tip of the screwdriver) provides the pivot point for the lever. The effort (force applied by the person) is applied to the handle of the screwdriver, while the load (the resistance to be overcome, in this case the paint can lid) is at the other end of the lever (the end of the screwdriver).
