During our lab session this week, we finally got to have some hands on experience with the Knex. Throughout the whole period, the three of us decided to get a feel as to which pieces we could use and how they can come together in efficient patterns. Shortly after experimenting for a while, Soichiro was able to start a bridge design using the Knex, so Disel and I decided to help him create it. When the lab ended Soichiro got to take his bridge home but Disel and I still have to create one for ourselves.
WPBD vs. Knex
Similarities: They both offer the option to place trusses of various sizes and gusset plates to hold them together.
Differences: Knex allows us to build into the third dimension and actually have a hand on feel to what feels sturdy or not. WPBD gives us exact numbers of the stress that is on each individual member. Knex limits us the sizes of trusses we can use, while WPBD will use any truss length to connect the gusset plates. In WPBD, you can change the size and material of every truss, which will affect the total cost of the bridge, but Knex don't have that variation.
