This week in class we start design our first bridge by K’nex. We first try the single structure and it end up becoming too weak and cannot support a lot of weight. Next we try the triple structure. The structure is strong in the middle and weak at two sides. By the end of the class we still work on the bridge. Next week is the first we load our bridge. We would try to get the most weight by the lowest cost.

The K’nex is mostly what I think in the last week. The K’nex do not have enough type of piece to whatever shape you want. The design is really limited. The piece have the same size, it also made the design become limited. If I get the chance to design a real bridge it would be different in many different way. The fist is the cost of the worker would be a new cost of the bridge, which is, not be part of K’nex Bridge. The second one would be the nature. The rain, wind, even sunshine can cost a different effect on the bridge. There also would be so percentage errors that happen on building or design. Make a really bridge is much harder than the K’nex bridge.
