My Balsa Wood Bridge

     For my Balsa Wood Bridge, I am going to attempt to create two different types of bridges, then work further on whichever proves stronger.

For my first prototype, I will be using a simple design of the truss bridge:

     I personally like the truss design the best because it is the strongest in architecture. The triangles formed in the center will relieve stress from the bottom of the bridge. It also uses the smallest amount of wood most efficiently. With the wood and mass that is saved by using less for a better design, I will have room to make adjustments and improvements.

For my other prototype, a very simple arch bridge will be made:

The arch bridge is stronger than most others, due to the curvature of the bridge. It will ease the tension from the center of the bridge, and distribute it to the sides.

As for my adhesive, I am going to test both wood glue and various epoxies, because these have different properties and bond differently than normal glue.

Because these are very early prototypes, I do not yet have exact measurements. As I progress through the stages of planning and building, the measurements will become clear,  also keeping in mind the rules and regulations provided by the B-Meister.
