Which of the following is NOT one of the six simple machines?

Explanation:
Think about what defines a simple machine: a basic device that changes either the size (force) or direction of a force. The six classic simple machines are the inclined plane, wedge, screw, lever, pulley, and wheel and axle. A hammer isn’t one of them because it’s a tool that combines these ideas rather than being a single, standalone simple machine. When you use a hammer, the handle acts as a lever around a fulcrum to multiply your input force, and the hammer head’s wedge shape helps drive or split material. In short, the hammer relies on simple-machine principles, but it isn’t itself one of the six.
