I’d even shoot for 1 or 2 a week if you’re really looking to make progress. And make sure that you’re modifying your design in stages. For example, if you had a compression failure, you shouldn’t strengthen your compression members and lighten up on your tensions because then you may get a tension failure and have to retest that compression modification.
Also slow mo all the testing and go frame by frame to see the exact point of failure

Or instead of getting a $1000+ phone, get a ~$250 digital camera that can do that.
Remember: MEDALS FROM REGIONAL AND ABOVE CAN BE USED ON COLLEGE RESUMES FOR DIVISION C! Good luck!

2019 regional/state meals:
Boomilever 6th
Thermodynamics 3rd
2020 regional medals:
Water Quality 3rd
Detector Building 3rd
1 other I don't remember I think it was 6th

Hey guys :) I am a new member of SO and Boomilever event. May I ask if there is any mathematical / engineering approach to building the Boomilever instead of just blindly building and testing?

Much appreciate any answer.

i mean yes there is a lot of math involved in boomilevers. in fact, if you are in high school and you take a mechanics course, that will help you a LOT in boomi. but blindly building isnt that bad. if you know how your device and you can find the greatest weakness spots on the device, you can get anywhere in this event. don't be afraid to experiment, especially with event. try different shapes, cross sections, wood, wood thickness/weights, glues, etc. always double check your measurements and be sure to be precise with each and every piece on there. oh and also dont use too much glue, the whole point of it is to be light but strong. let me know how it goes!
it's not about the medals; go out there and have fun. make progress, learn a few things and have one heck of a time; that's all that matters.

I think my message somehow got deleted before I posted lol.

I was going to suggest looking at Euler’s critical load. You don’t have to actually use the formula to calculate anything, but it’s principles can really help with your fundamental design.

So do you guys think that rule 4.i. will actually be followed, especially at regionals? Specifically the second part, "Teams will be given a choice of which testing apparatus they will use," could potentially be helpful at regionals.
I imagine one tester being out of plumb, everybody wants to use the other one, but the officials say no, big hassle.
This is a bit unrealistic, I know, but I was curious to what you guys think. :D

Has anyone tried using dowels for tension members? Would they be inherently strong just because of the even and cylindrical design?

Thanks
in advance.
Happy to be here
