Drawings
The part and assembly drawings below were used to construct and assemble the bridge
Construction
.The construction of the balsa bridge was done in 2 major sections; the bridge and the brace. The bridge was made exclusively of balsa wood pieces and wood glue. The pieces were cut with a box cutter and a straight edge and assembled after all cutting was complete. The brace was made of a combination of materials and included a locking mechanism to hold the bridge in the raised position. images taken during the construction process are shown below
