This week in lab we looked at each of our designs and
decided which we thought was the best design that had the smallest strength to
cost ratio. This ended up being Ling’s bridge. We did tweak it a little bit and
added some aspects of George’s bridge into it. The goal for this week was to
use the Knex pieces and to try to build a bridge that we thought would
accomplish this goal. Next week in class we will be have a competition in the
class to see which group’s bridge has the smallest cost to strength ratio. Some
problems that we came across were that we each thought that our initial bridge
designs were the best, so we had trouble coming to a consensus. We discussed
and started building and realized who’s was the best and what we could do to
improve it.
