Students groups use balsa wood and glue to build their own towers using some of the techniques they learned from the associated lesson. While general guidelines are provided, give students freedom with their designs and encourage them to implement what they have learned about structural engineering. The winning team design is the tower with the highest strength-to-weight ratio.
· Not all wood is created equal, and choosing the right balsa for your tower is important to increasing the strength of your tower. Examine each piece of wood closely before choosing it for your tower. A strong piece of balsa wood to use comes from a dense stick. Check the denseness of your stick by doing a squeeze test.

The best balsa wood tower designs require the sparing use of glue and other liquid adhesives. Many competitions require you to have your tower weighed, and excessive glue adds a considerable amount of additional mass to a tower. Do not use glue to fill gaps, and make sure all measurements are exact.

· Make it isotropic (even though wood is not) and use caution in the analysis. Your instructor should be able to show you how to add a material. If you can't figure it out - post back and I will find video instruction on the process.
Wood: The bridge members will be composed of balsa wood, with no member having dimensions greater than 1⁄4 inch by 1⁄4 inch, and 24 inches in length. Exceptions are made at the joints (See below for details). Note: A member is defined as a single piece of balsa wood. Glue: Wood glue used for carpentry and residential use.
· *Edit - Here's PART TWO, which goes over the final testing results* Recently, in my engineering statics class, we were assigned the project to build a truss tower made from 1/8" x 1/8" strips of balsa wood. Sure, some desperate student will probably try copying this design, but I believe in open information. I'll update…

· This balsa tower was 12 inches tall, 8 inches wide at the base, and tapered to a 2 inch square at the top. I only have about forty pounds of sand, so I ended up adding any heavy object in sight to the bucket. After putting in the ceramic mug used to pour the sand, a chain, paper weights, the total weight supported was 50 pounds.
with ModelSmart TM. ModelSmart is a new software program designed to introduce middle, high school and college students to basic engineering concepts while reinforcing their math and science skills. Written by a professional engineer, ModelSmart allows students to interactively design and test balsa and bass wood structural models of bridges, cranes, towers, and all kinds of structural systems ...
The tower that has the highest load to weight ratio (load before failing divided by the weight of the tower) wins! Rules: Maximum team size: 1 (one person per team) Only 1/4 inch balsa wood cross beams may be used, no balsa sheets will be allowed (balsa cross beams can be found at hobby stores, home improvement stores, and many other places)
This tower-building class pack includes enough materials for 24 competition towers, including balsa wood, glue, "B" sized graph paper, student instructions, and a teacher's guide. Science education products incorporate applied math and science principles into classroom projects.
The team's problem is to design, build, and test a structure made of balsa wood and glue that will balance and support weights. The team is allowed to use materials other than balsa wood and glue ...
The Tower structure must be constructed of the balsa wood provided as well as the glue provided. No other materials may be used. The Tower structure must hold the loading block a minimum of 50 cm above the testing base. The Tower must be constructed such that only the Loading Block supports the chain and bucket.

Ochroma is a genus of flowering plants in the mallow family, Malvaceae, containing the sole species Ochroma pyramidale, commonly known as the balsa tree.It is a large, fast-growing tree that can grow up to 30 m tall. Balsa wood is a very lightweight material with many uses. Balsa trees are native to Mexico, Central America and South America.
Balsa Wood Tower. OBJECTIVES: 1. Learn basic engineering principles. 2. Identify basic shapes that form structures. 3. Design a tower for structural strength that will hold weight. 4. Use the student made design to construct a tower using given materials. Students will work in groups of two to design and build a balsa wood tower.
· Balsa Man wrote: There is, I believe a big downside to the rectangular configuration (with flat, parallel sides), though; overall tower stability. With the load on top of the tower 50cm above the base, only a tiny amount of bucket sway across (perpendicular to) the plane of the flat sides will create a force that will act to tip the tower over.
