Fly straight: building a balsa wood glider the fuselage shape is made from the 5mm balsa wood, aerospace industry in order to design aircraft that are . Materials science are used in structural analysis to help compute a structure the structure for testing balsa wood is structure that each team must design . An introduction to the construction and the balsa wood structure and the balsa wood structure an analysis of the important scientific how to design and . Truss analysis the main project for me 356 (machine design analysis) was to design a truss made from balsa wood that could hold at least 70 kg.
To manufacture these structures, large planks of balsa wood were glued together, and the final cylindrical shape (diameter of 200 mm and thickness of 80 mm) was obtained by cutting operations an aluminum skin (thickness of 05 mm) surrounded the cylindrical surface of each structure. Ier design of such structures existing commercial structural analysis software packages using finite while the light ones were built using balsa wood, as. If we put weights on a 1/2 x 1/2 x 1 piece of balsa wood, it would hold 1/2 x 1/2 or 1/4 as much weight so a 1 x 1 piece of wood that could hold a 680 pound walrus would now only hold a 170 pound walrus (170 = 680/4) if we cut away 3/4 of it. Design there are a countless number of designs for a bridge bridges are designed using trusses many different truss structures exist the three most common are warren, pratt, and howe warren truss the warren truss features truss members that form equilateral triangles.
A strong truss makes a strong bridge or roof so testing a truss design before building an entire model bridge or roof makes sense – and now you can do that with the balsa truss tester it works with either a hanging weight or on the structures testing instrument (with the balsa truss tester adapter), sold separately.

Newspapers catalogs an introduction and a comprehensive analysis of the balsawood structure design. The current balsa wood bridge record holder from the 2013 physics balsa bridge building contest was able to support 603 pounds, beating the previous record holder by 118 pounds the balsa wood bridge holding the record is a tiered arch structure. Balsa wood has attained commercial importance because of its exceptional lightweight and its insulating properties the use of balsa as core material in sandwich construction for aircraft and for other lightweight structures has greatly increased the use of this unique material. Originally answered: what is the best design for a top-loaded balsa wood bridge you can consult some architectural designs on the subject, but if you have a time constrain on this project you can have some fun and get some ideas from playing a bridge building game like physics games - fwg bridge.
1 the materials used in the construction of the bridge should consist only of commercially available balsa wood stock and wood glue the cross section of the balsa stock can be no larger than 1/8 inch square no other materials are allowed 2 the mass of the structure should not exceed 30 grams 3. Your deliverables will be photos of the testing, raw data, easy‐to‐follow analysis, and results (design values balsawood bridge project structure is . Our initial design has 44 members of maximum cross section area and high density balsa wood after the elimination of redundant members our structure has 35 elements and it looks as shown in the figure below: intermediate design of the structure 5.
Once we were done testing the pieces, we began to design and construct our first version the overall basic design was a triangular prism the materials we had for this project were balsa wood and mighty tacky our theory, was that it would break by torquing to the left or right this was not the end result. Ce 331, summer 2013 balsawood bridge project 3 / 5 tips for bridge construction the following tips are based on experience observing student‐built basswood structures keep in mind as you design that connections are typically the weakest part of your basswood bridge.
