Exploration
Now that you've finished the build, test what it does. Explore with your build and then answer these questions in your engineering notebook.
-
What does this build do? Explain with details.
-
How might this build be used? Explain with details and sketches.
-
Does the build have a mechanical advantage(s)? If so, how? What is the mechanical advantage? Explain with details.
-
Which engineering terms are needed to explain this build to someone who has not seen it? Explain how each term describes this build.
For example, if we were designing a roof for a house, I would say that the engineering term "pitch" is needed to describe this roof. Pitch describes the steepness of the slope in the roof. I could then use this term to better describe what I was building. Here are some suggested terms for the mechanical advantage exploration: "gear ratios", "idler gear", "speed", etc.
