The lecture I experienced from this week was abundant and useful. I knew four major components of a truss bridge. And I familiarized with my team member how the K'nex from shapes. I basically knew the steps of designing a truss bridge in reality from the K'nex, like making an idea; choosing materials; build as a model; budgeting; testing; editing and etc. There must have a lot of different in detail when I am doing a real project. And for K'nex, I felt the materials could predetermine how the bridges look like. I didn't feel that when I made a bridge via WPBD. Besides, K'nex is a real and touchable toy and lots of problems will come out. For instance, in WPBD, the truck has such a strong climbing ability. It can still pass the bridge when it is down to the bottom of canyon. However, it will never happen in reality. So when I test the K'nex bridge, it will collapse if it can hold the weight any more.
I also listened a speech in class. It was a speech by Mr. Jay Bhatt, our engineering research librarian, about the most efficient way to look for engineering-related books from Drexel Libraries. He demonstrated the way that searches different resources in the class. I felt that that made my study much easier than before.
For next week, we are processing the K'nex. We will pick the best idea from our team and build it with K'nex.
