Last week, the Engineering Librarian came to lab and shared resources that will be helpful in the future. The librarian also went over how to efficiently use the Drexel University Library website. Students were then able to begin using Knex to create and design a bridge. Throughout the creating process, modifications were constantly brought up and made to the bridge. The groups were permitted to take their designs from lab, however; the group did not take any additional pieces. Next week, the group will have to take additional pieces in order to work on and make any necessary changes to the design.
West Point Bridge Design seems more realistic. The program show the specifics of each member used and it also calculates the total cost of the bridge design. The Knex allows for more of a "hands-on" design. Members can easily be taken off or added to the design and an actual 3-d model can be observed. When it comes to changing the size of a member, using Knex, the designer has to locate a piece of suitable size which may not always be available. On West Point Bridge Design, the designer has to simply draw a member that fits.
