PRESENTATION OUTLINE
Problem: How are we supposed to build a strong popsicle stick bridge using only 200 sticks and elmer's glue?
There are three types of stress we are supposed to go over, compressive stress, in which you press and object together, tensile stress, which is stress caused by pulling apart, and shear stress is the result of opposing parallel forces across a flat area
The first thing engineers needed to know was, "How do we distribute stress and weight equally?" Their solution was the truss bridge. The design allows it to spread stress evenly, putting the diagonal members under compressive stress and the inner objects under tensile stress.
And, based on the previous slide, you can probably tell that we decided the truss bridge was the best.
Even though we had the right idea, we didn't finish the bridge because we made a lot of poor decisions, and being down a member didn't help our case.
The advice we would give based on experience would be to stick to a simple design and use your time wisely.
If we were to be given a second chance, we wouldn't stray much from our original design, except for the building order.
