What Is a Strong Balsa Wood Tower?

The strongest balsa wood towers have a high strength-to-weight ratio. These towers are lightweight, but they also have added beams that can support heavy weights.

According to Teach Engineering, balsa wood towers should have a strength-to-weight ratio that can support weights without buckling under that weight. The tower must be strong enough to handle lateral forces, such as wind or earthquakes, and it should also be able to hold much more than its own weight. Weights are placed on top of the tower, so the tower must be able to hold the weights up.

Balsa wood towers are created by cutting balsa wood into pieces and gluing the individual pieces together. Epoxy glue is typically used during this process because it dries quickly. If epoxy glue is not available, superglue can be used in its place.

The strongest balsa wood structures are able to hold the weights being placed on them without moving, bending or buckling under pressure. To help prevent buckling, additional support beams should be added, as these help to reinforce the structure's width and height together with its main weight-bearing beams. Most balsa wood towers have only three or four sides that are then glued together and reinforced for support.
