what are examples of a class three lever?

Question

adrianluvvsyouu2 · Answer

Class three means:

- Fulcrum is at one end
- Weight/load is at the other end
- Force/effort goes is at middle

I guess an example I can think of is my own arm lifting/curling something, the weight is at my hand, the fulcrum is my shoulder joint, and the force is being applied at my elbow, which fits all the criteria

Correction, I think the fulcrum would be my elbow in this case, and the force would be on my bicep, so I'm not sure that example actually applies here. Maybe tweezers pinching an object is a better example
