WPBD vs. Knex

The similarities between the products of designs from WPBD and Knex are the manner in which you would build the bridges. The designs that we made in WPBD could be some what implemented into the “real” bridge that we will be making with Knex. Using WPBD we were able to learn how to make a good bridge, even if we do end up pushing the limits. WPBD was able to show us the best way to structure a bridge so that it will not collapse. We can use these ideas when we build the “real” bridge using Knex. In my opinion on of the greatest similarities is that using shorter bars gives the most support. Also there is the aspect of the strength to cost ratio.

            The differences between the products of designs from WPBD and Knex is that in WPBD you can push the bridge to the absolute limit, where if we tried that with the Knex the bridge would collapse with the slightest amount of force. Also using the WPBD program there was no chance of the the bars slipping out of the gusset plates, on the other hand with the Knex pieces the gusset plates are not completely secure, it is possible for the bars to slide out. Finally, the exact strength to cost ratio is not the same.
