Re: Robot Arm C

Off topic, but can anyone give me the dimensions of a standard half-gallon milk jug?
~ 97mm x 97mm x 210mm
Is there a reference to the standard number and regulating agency?

Here'sthe best I could find!

Re: Lever Tasks

The clarification on soinc.org disagrees with my understanding of simple machines. Here is one website that explains it. Be sure to read the last section at the bottom of the page. Mechanical Advantage (MA) is a general term that includes both IMA and AMA. Ideal Mechanical Advantage (IMA) and Actual...

Re: Lever Tasks

You're on the right track, with one slight mistake. IMA is what the mechanical advantage would be in a "perfect" system ignoring friction. It is calculated using length/distances or velocities (velocity =distance/time)) IMA = Distance traveled by the Effort / Distance traveled by the Load or IMA = L...

Re: MagLev C [Trial]

A major advantage to mag-lev is the tremendous reduction of friction in the vehicle/track interface. The introduction of wheels in the design would tend to negate this advantage and thus decrease performance. On the other hand, I would be surprised if real-world mag-lev vehicles don't use some type ...

Re: Gravity Vehicle C

can the pencil be used as the release mechanism? Almost the exact same issue came up at one of the national tournaments (Sorry, I don't remember which tournament, but the vehicle was dark green, the distance was adjusted by adding/removing gauge blocks and a metal rod was removed to start the vehic...

Re: Bottle Rocket B

the 2 litter fit perfectly but the 1 litter doesn't I had no luck in finding a 1 litter bottle with a 2.2 nozzle. All the bottles I got had 2.16 in nozzle size A 2.16 cm nozzle inside diameter should fulfill the "approximately 2.2 cm" requirement stated in the rules. Others may be able to shed more...

Re: Gravity Vehicle C

Short wheelbase=lesser yaw stability
Long wheelbase=greater yaw stability

With a shorter wheelbase smaller errors in alignment between the axles/wheels increase the curvature of the vehicle's path. If you make the wheelbase too short, you can have problems making the vehicle travel a straight line.

Re: General Discussion

The fact it is publicly available is probably a big issue. Regardless, those are rules from 5 years ago. Permission is given in the rule book for a school to copy the rules for use WITHIN the school. Putting them on a website is probably not an issue as long as they are accessible only to teachers,...

Re: New York State 2008/2009 Results?

I need the New York State 2008 and 2009 results. Its supposed to be here You can try the Wayback Machine . I found the 2009 Div. C Results and the 2008 page you listed, but not the PDF file with the 2008 complete results. I spent only a very brief amount of time looking. You may find it with a litt...

NY - coaches get a free copy when they register their team ALL registered teams get a copy of the rules, regardless of what state they are from.
