Re: Designs

In regards to the question of whether or not we can use multiple matches and count them for multiple transfers (the idea of repeating transfers in general), I think the answer was provided very clearly by someone earlier in the thread. Some claim that this could be considered the same "action&q...

Re: Designs

Chalkers, I've sent in many requests for clarification this season for Mission, and haven't received a single response. Some of them have been 2 months or so. In the past, I've sent in MANY clarifications and received responses so I was wondering if you know what's up. Is there some horrendous backl...

Re: MagLev C

Who is going to try and pick it up? The competitors? Why would they when they know that is what their car is going to do? The judges? Why would they want to risk damage to the competitors vehicle? It is their best option to avoid interfering with the device during the running phase. Phillip, I unde...

Re: MagLev C

Chalker, Based on my experience in the event, I'm somewhat familiar woth how the event is scored, but where in the rules does it describe which scores contribute to the final score? It's my understanding that the event supervisor selects the best time score and the best mass score from the two runs,...

Re: Mission Possible C

. Inverse transfers, I love 'em! Legal. Nothing in the rules says everything has to be "turned on to transfer." Think about it-- ENTROPY is your friend. Stop things. Block things. Cool things. (Just don't have any motors running beforehand). It's easier, trust me. I agree with this, but d...

Re: Mission Possible C

I also would not count a commercial battery as Chem -> Elec not because it is not student made, but because prior to the start of the event the battery already had a voltage difference between the poles which represents a preexisting electrical potential. To count as Chem -> Elec in my book one wou...

Re: Mission Possible C

In the first case the electricity is running the motor, the second time the electricity is creating light. The black box in both cases would be the battery, you cannot count the chemical reaction because you didn't create it (if you used a lemon and made a battery then you could count it). In the f...

Re: Mission Possible C

Answering what a transfer is would be just restating the rules, it probably won't be addressed by any of the national judges. Once you have been in the event and competed you will understand what I mean. This event probably has the greatest learning curve of all of the events. Let me give you an ex...

Re: Mission Possible C

From your link: "When zinc is inserted into an acid, the acid begins to eat away at the zinc, releasing hydrogen gas and heat energy. The acid molecules break up into its components: usually hydrogen and other atoms. The process releases electrons." The reaction at the cathode may require...

Re: MagLev C

This may be a little early in the game, but we have built and are testing an early (and nowhere near final) 2kg prototype that is controlled via rheostat and have noticed a peculiarity that is making long runs (around the 15s mark) very difficult to control. It seems that, even with friction nearly...
