If we were able to get a analysis of the our KNEX bridge just like we got in WPBD, I would be able to tell what exactly is the problem with the 180 groove gussets. Like in WPBD, I wish I was able to see what the most strained or least strained pieces were, which pieces had the most tension in them, so that we knew how to change our bridge with a better perspective. Though we would not how to do further calculations with these numbers, since we have no prior background, but if given formula's, finding out more in depth analytical numbers would be greatly appreciated. But, for now we have to make best use of our eye, trying to watch each piece as more and more weight is put onto the load, if we are sucsessfully get three good angles at the bridge, we might have a good chance of seeing where out bridge exactly failed from.
Last week the entire class performed loading tests on our bridges. We came out with a lousy and pathetic 5 lbs. we partially knew that we would score low because of the 180 groove gusset plates that we used. Yes, they added a versatile part to our bridge, but in the end it was just too weak of a part. We did not just have once of them our every gusset plate on our bridge was that one, which amplified the instability of our bridge even more. This week we hope to construct an entirely new bridge that holds alot more than a measly 5 lbs.
