Re: Efficiencies
Im pretty sure he/she means the base of the tower.

Re: Efficiencies
i meant the efficiency of the tower as a whole

Re: Efficiencies
They were talking about your second question.sciolyswizzle16 wrote:What are some of the best efficiencies you guys are getting?
And if our base keeps breaking, what would be a good way to fix it?
As to your first, 40 should be very competitive.

Re: Efficiencies
we have the exact same problem. in general we are trying to make our top lighter because if the base breaks first, it means we have unneeded weight at the top(so ideally, a tower should have the base and the top simultaneously break?)sciolyswizzle16 wrote: And if our base keeps breaking, what would be a good way to fix it?
to make the base stronger, you might want to add one more truss on each face of the base, or make the main sticks on the base less slanted. You can do this by making the 4 main sticks on the top slightly slanted, and changing up your dimensions. That way, the top will have slanted sticks and the base will have slanted stick but the sticks on the base will be less slanted.

Re: Efficiencies
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
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.

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?
