Following the initial design evaluation, some testing was done to understand how the
bridge would hold. We used our calculations and chosen widths for each member of the bridge
panel and designed the 1st implementation shown in the image. This implementation consisted of
both 1/8th members. This made the overall design very weakk as the 1/8th members were very
weak.
This design weighed around 38 g and only carried a load of 8lbs. So for our next
implementations, we thought the same design, but made the widths of all the members bigger. As
this would help us actually carry the design load and maybe more. The CAD model for this is
given below
This design weighed around 90 g and was much stronger than the previous iteration.
However, this was too heavy a bridge even if it held the design load and more than that. Hence in
our next iteration, we reduced the thickness in some members and changed the style of our cross
bracing. This was our final design, and the CAD model is given below:
This bridge weighed in at 85 g and held a total of 19 kg, and failed at 20kg. Hence,
making our efficiency 229%, and helping us finish at 2nd place for the competition
