Answer 1

The example that represents a class 2 lever is **tweezers plucking hairs**. In a class 2 lever, the load is between the effort and the fulcrum, and in the case of tweezers, the load (the hair being plucked) is in the middle, with the effort applied on the handles and the fulcrum at the pivot point of the tweezers.
