Competition for state But just out of curiosity, what dimensions of wood did you use for the base legs? I use 1/8 squared.SO4L wrote:I just tested my first 2 towers of the season at an invitational and they both held 15kg. The efficiencies were 14.5 million and 15.2 million. I think i have my design down, now I just need to experiment with different types and dimensions of wood.

Re: Efficiencies
Both divisions should have medaling begin at ~20 g/kg^2. The rules are tougher for C, but there are also usually better builders.Arthur wrote:what efficiency do you think would be needed to medal at states in pa?

Re: Efficiencies
Yes that sounds about right. With practice and good jig designs (and that is crucial) as well as good wood, whether it be balsa or bass, state medals should start around there. By that u mean top 4 i suppose?

Re: Efficiencies
PA gives out medals to Top 5 (and I assume most other states do the same thing).

Re: Efficiencies
I'm sure this is a relatively stupid/simple question, but is there a certain way you all pour in the sand. If a lever system is used to let the sand fall in, would you want to go slow, then faster, then switch back to slow? Letting the sand in slow seems like it would make your tower sustain the weight for longer times, but faster streams seems a bit all of a sudden.
And if there is a manual sand system, then I would assume you would try to pour the sand around the bucket evenly, so there are no mounds, and try to do it as quick as possible?
