Re: pic: Wheel
Not to give the textbook mentor answer, but if students learned in the process, I see that it has more benefit than just weight saving. If they didn't... well it's still pretty nifty.
I too was wondering why the rim thickness was kept so thick, until I realized the center spokes of the wheel are only about 3/4" or so wide (relative to wheel width). I also realized that's what you meant by "a lot of material was removed from the back side".
