  1. I'm back again with another question! So I won 1st in Director's Choice in the State Science Fair and I was offered to continue my research in a lab setting! I understand that continuing to rely on bamboo rods would be impractical, they absorb water, are prone to igniting on fire, void in rod area of larger species, etc., so I'm thinking about research on bamboo fibers. I would have to do extensive research on this since I really don't know anything about weaving(?) fibers, but if anyone has any suggestions that'd be great!
  2. I actually got first in Materials Science! I'm supposed to give a presentation to the Rotary Club this Saturday, and the GA State Fair is next month! Bamboo withheld more mass than the steel ; I actually was unsure about which size rods to use since bamboo is really light while still encompassing more surface area, while steel alloys are so heavy. So I just made a limit of less than 1 pound for both. The engineer who judged my project threw some really hard questions though-- he asked about the heat capacity and the time it would take to collapse, both of which I did not test. Any tips on how to test this?
  3. Steel has strong tensile strength, but somewhere in my research I found that bamboo fibers have a pretty high tensile strength too. I'm using thin concrete models
  4. I was so afraid I wouldn't get any replies before the research plan was due, but yea i won't double post anymore lol
  5. Thank you for your reply! I actually went with this design and added more kettlebells on a chain until the tensile ends broke
  6. I'm an 8th grader. Actually, I'm not sure if this belongs in this forum, either, but I'm doing a science fair project about bamboo being an alternative to steel reinforcement in concrete walls/buildings/infrastructure. The thing is, I'm having trouble with testing the models themselves. Should I just start randomly pounding the models with a hammer or some bricks? Power hammers are too expensive and I don't have access to one (not sure how I would test the models with that either). How can I prove that bamboo is as efficient as steel in reinforcement?

I'm thinking about maybe motorizing the hammer with Arduino and some bits but wouldn't that be too weak to support a whole hammer? Any motor recommendations? What are your thoughts?
