Explanation should include
- defining the term unifying principle (each energy system uses force transformers that work on the same physical principles, with an input source, coupling device, and output load)
- applying the unifying principle to
- levers
- pulleys
- gears
- pressure systems
- transformers.
Process/Skill Questions:
- What is a source (input) to the unifying principle?
- What the relationship between a coupling device (transformer) and the unifying principle?
- What is the relationship between a load (output) and the unifying principle?
