good job & welcome to scioly!
HI. I"m from Montgomery in Division B. My bridge did well in practice, but failed in competition. I chose a light piece of wood that happened to be very weak. I spent a long time building my bridge with my dad. We carefully cut, glued and sanded the wood. We even weighed the pieces of wood to find the lightest piece. In practice, i got as high as 1200. But, in competition, we got four hundred something. That's disappointing, but I learned a lesson. But, I learned a lesson. lighter isn't always better. Sanding too much is also bad. Next time, I will try using medium density balsa wood, or practice loading quicker. I will also be conservative while sanding. I can't help but think that we could have easily beat mt. hebron had I chosen a stronger piece of wood. But, wood is an organic product. It's unpredictable and not uniform in quality. this is what makes building hard. It's not linear like taking a test.
By the way, which team are you on? Montgomery?
you might want to move this to the Bridge Thread, they are really helpful. And also, wat new horizon said, that you should try being consistent. There are also a lot of factors besides "lightness" and how "heavy" the wood is. sanding isn't always something you have to have either, messes up the joints
