Here is the solution they gave in the textbook, but certainly not the only one. The instructions don't put restrictions or conditions other than to attach the candle to the wall. It doesn't say you have to use all the materials. In the solution above, it appears the candle has been lit and drops of wax hold the candle upright, though that isn't clear. There may be a tack on the bottom which isn't shown (that's how I would have done it. You don't need the matches at all in that case. Actually you don't need the box either if you just tack the candle to the wall through the wick.I wonder how many engineering or design students couldn't visualize this rather unchallenging problem? I think those students would be weeded out by the end of the first year, hopefully.
Did you know that the best Systems Analysts don't come from the programming community? Or any other technical field, for that matter. They come from the arts: photographers, artists, filmmakers. Technical people never seem to be able to see the big picture amongst all the details that interest them so much. They tend to stay in their boxes.
