This document discusses machines and their definitions. It begins by asking the reader to think of different types of machines and provide examples. It then provides a dictionary definition of a machine as an apparatus with several mechanical parts that work together to perform a task. The document asks how this definition compares to the reader's own definition. It discusses the primary and secondary functions of machines, noting that some machines can have more than one primary function. Finally, it asks the reader to consider non-physical things that function like machines by having component parts.
