axles, hubs, spokes, and rims

Looking for a metaphor…..Eileen uses the notion of a wheel to teach about culture, and we’ve been discussing the relationship between culture and discourse – how we can distinguish between them, and also separating out dynamics too, even though we know all three are braided together.

I found this diagram of the parts of a bicycle which identifies the center of the wheel as a hub. I didn’t know she had a bicycle in mind when she brought up the notion of a wheel; what I envisioned was a covered wagon’s wooden wheel, the center of which is also called a hub. But we were also talking about axles. There are different kinds, from passive connecting rods to split, driven axles that actually transfer power from an engine to the wheels.
