The glue will dry in about half an hour. Look for a medium- to high-density balsa. Use pieces of masking tape to tack down the drawing of the side of your bridge. Together, they cited information from 7 references. Co-Authored By:. In this Article: We are doing this in my engineering class.
On the side-view drawing, write in all the measurements for easier cutting. Choose your materials. The best approach to doing this is to first line up the desired piece of balsa wood over the area you wish to connect. Share it with us!
Yes No. Organize your materials. This instruction set will teach you how to design and construct your own bridge made out of balsa wood.

For the best results make sure the diagonals are positioned so that the lower connection is moving out from the center of the bridge. Include your email address to get a message when this question is answered. Plus, these are two of the simpler types of bridges to engineer. If you want to, you can dilute it slightly with water.
Next line up the newly cut diagonal piece with the area you wish to connect it to if the piece lines up continue to step 8 if not then go back to step 5 and 6 and repeat them until it fits appropriately. After you finish your rough draft and decide what type of bridge to create, use it to make a scaled rough draft.
Now your bridge is complete and is ready to be tested. This will make it easier to grab and use them. Now it is time to connect the two trusses to each other. Put a thin line of glue on each edge of the roadway.
These will serve as the vertical supports for the trusses. Most balsa bridges are types of truss bridges or arch bridges, as the wood lends itself well to this type of construction. Tell us more about it?
