A playground teeter totter is considered what type of lever?

Explanation:
When classifying levers, the important idea is where the fulcrum sits relative to the effort and the load. In a teeter totter, the pivot is right between the two ends where people push and where the weight sits. That setup—fulcrum between the effort and the load—is what defines a first-class lever. Second-class levers have the load between the fulcrum and the effort (like a wheelbarrow), and third-class levers have the effort between the fulcrum and the load (like using tongs). A pulley system isn’t a lever at all. So the teeter totter is a first-class lever.
