Re: Technical Problem Solving C

For the rules of this event, it states that it will be covering decomposition rates. Is that relating to kinetics in chemistry and using the rate laws?

What are some good materials to make a ramp out of? I was thinking of making a curved ramp over a flat ramp for obvious reasons but creating a ramp out of a bendable material is the tricky part. Would aluminum channels glued onto a wooden base be efficient?

I think this is one of the simpler tasks this year. (The others are quite tricky, though, or so I've heard.) I did MP last year. Last year they gave us a choice between hydraulics and pneumatics, and we chose pneumatics. We went to a pharmacy and got some syringes, two to be exact. We stretched a t...

Re: Scoring

Our team is attempting to complete both of the 50 point tasks, however there is a semi-high rate of failure. We were wondering if we can build a couple of 20 point tasks into the MP and make a spare TSL in case the 50 point tasks malfunction. If we were to decide on the day of regionals to use the ...

What if the ball roles into a funnel and then drops onto a straight track. The (circular motion) of the funnel, the dropping of the ball is the conversion from circular, and the track causes it to change to linear?

I have found that using a heat only thermostat from Honeywell works well. I just purchased the cheapest one and I connected two leads to the electrical connections and it will close a curciut. <http://www.amazon.com/Honeywell-YCT30A1003-Heat-Only-Thermostat/dp/B002PNE00Q> this is the link for the m...
