It's my bom

And I don't mean, as the Brits say, "Bum" :)
I'm not trying to be naughty, just posting a part we made in class. Attached is what we had to match, which is basically a weight given to us knowing that the part is made of Copper.Therefore, it had to weigh 4.76 lbs. If our modelling is off, that figure would be off. So woohoo mine matched!
Why is it important?
Say you had to make 10 000 parts like these for an airplane. The part would fit into a specific area that HAD to match the size for it, as everything would be built around that measurement. Also, weight. If you are off, over time, with more of these parts, the weight would be a LOT more. With airplanes, etc, the engineer probably built these to be as weight efficient as possible for what the part needed to do. So adding more weight unnecessarily adds up over time and can lead to inefficiency.

An incorrect part weight/measurment also means it affects cost. If you are making 10 000, and all of a sudden instead of 4.76lbs it costs 4.78 or 4.80lbs and it costs .10 or ten cents for each part, you're off your budget by $1000 because someone didn't do their job well or overlooked the spec.
Tonight, I was also reading about how Feynm@n did discover that the management at N@S@ didn't feel as comfortable about the Ch@llenger being ready for launch as some of the top engineers did, and so due to gr0up-think, the disaster was allowed to occur. So the small things do matter. They just thought he was being a pest and took his surveys and tests that he was doing independently at the time and shoved it away. If only they had listened...
On the other hand, (which is what the book I'm reading is about), such behavior in groups can help us to understand why humans do such things and if they are effective, which in turn is being used for things like understanding how we can make things like r0bots (yes, here we go again) behave more like humans.

So anyways...because I couldn't do the other parts of the homework, I just played around with the rendering.

  1. Solidworks looks like fun! I like flat shaded look of the second image. That is crazy about the Challenger. I remember when that happened, everyone was in such shock/horror. My second grade teacher told us she actually tried out for the "First Teacher in Space" program, which was aboard the Challenger, and got rejected. Supposedly it was freakishly cold that morning, like a perfect storm of events that caused the catastrophe. Its incredibly tragic..

  2. Yes it is! I just only tonight was reading about it in this great book called
    "The Perfect Swarm" that I'm almost through. It's all about that kind of thinking; when it's
    useful and when it went wrong.
    My next book is on AI and after that it's a Feynman book! :)
