Week 4

This week in lab the task of building a bridge was given. This bridge must span at least two feet and must be able to support weight. These bridges will be made out of Knex. One bit of useful information that was learned is that it is better to use smaller bars because they are less susceptible to bend and therefore are stronger than longer ones. Then we were given an opportunity to “play around with” the Knex pieces. So we tried building bridges, each of ours a different style. The goal or our assignment for next week is to design a bridge with the best “Cost/Failure-Load” ratio. This means that it has to be the cheapest bridge that can hold the most weight. Hopefully, we will all come up with different designs that we can use to make one bridge for the end of the term that works really well.
