     This week we learn how to use the west point bridge design. It is easy software to work with. It basic gives us tools to design a real bridge. In WPDB we can design a bridge by changer different shape of the bridge. There also different kind of size and type of martial that can choose to use. WPDB also have a tool that alone you to test bridge. That is really useful. By testing the bridge I can easy know which part need to improve. I finish my first bridge on class. That is really interesting. Next week we will continue working on WPDB and bridge. We still need a lot of work on Design Bridge. By working with team member can help get a better bridge designs. There also possible we will get a guest speech this weeks talk about bridge. I am looking forward to hear that.

There is some question I have that could be answer by the guest.

As we now are talking about cost of the bridge, which bridge was the cheapest one over all?

It there are rule of which kind of bridge is use what kind of material to build it, or which material  can be only use on one kind of bridge but not another?
