Re: Junkyard Challenge (C)
Plus you have to keep in mind required or supplied materials, if the event supervisor deems them necissary. Please excuse my spelling. I know the event suporvisor sends out a list of them to all of the competing teams, but if the builders are not informed or misinterperate, that can make or break a team. Accuracy and incorporation of the mystery material are important, but attentiveness is also a big part. Atleast I think that's what I'm trying to get at.

At our invitationals, our Mystery Material was an empty soda can.

Re: Junkyard Challenge (C)
Definitely check your state websites for rule clarifications about junkyard, everyone. I know Indiana posted a list of six items which the mystery material will be one of. That makes the event a lot easier, so you would certainly want to know if your state has done something like that.

Re: Junkyard Challenge (C)
i was reading the rules and it seemed unclear whether a ruler was allowed. The rules state that no standard scales nor scale parts may be used. Does the mean scales for weighing or all scales. And if a ruler was not allowed, than wouldn't commercial graph paper be not allowed because it can be used for the same purpose, just without numbers to mark length.

Does it say a ruler isn't allowed? I doubt that but I guess i could have missed it. A ruler is a big part of my model...I was able to use it at Lake Conference this year without getting put in one of the many bad tiers that this event has. However, the instructors weren't very knowledgeable on this event...so we could have just gotten lucky. I'll read the rules again tomorrow.

Re: Junkyard Challenge (C)
From the rules:
As a disclaimer- Just because I think this way doesn't by any stretch mean that an event supervisor might agree with my understanding of the rules
My personal inclination is to believe that a ruler would be allowed, as long as it did not come attached to a device meant to measure weight, this would make a good rule clarification. While I believe that in this clause they are referring to scales designed for weighing things, a ruler is in some way a scale of length, and it is a commercial device. For this reason I can't really say for sure... but I would tend to think that most judges would agree that the rules refer to scales for weight. Otherwise, rulers, metersticks, and all measuring tools would be banned.a. Commercial scales, components of commercial scales. Students must be able to demonstrate that their
components did not come from a commercial scale.
b. Commercially calibrated weights and masses are prohibited as construction materials but may be used as
tools.
