Re: Potential Energy calculations requested
Here is a variation on the question, from a different perspective. Has anyone tested the amount of energy that is lost or would be lost if a track were constructed with an arcing left turn designed to allow the track to be longer than the longest straight measurement of your venue? An offshoot of th...

Re: First time running the Race
Things to help the first time organizer: 1. Supplies - get a 9 dollar orange plastic 3 drawer storage cabinet with wheels from walmart. Use it for tape, pens, stapler, paper supplies, cords cables, connectors, tools, spare parts, etc. This will help keep things organized and visible on race day. 2. ...

Re: Sources for Plaques/Trophies UPDATED WITH PICS
We had been using a local vendor, but when I realizes I could get the same resin car trophy for 7 dollars online at trophydepot.com that my local vendor charged 12.99, I tried them out. Free shipping, and I was able to award first through fifth for tigers,wolves,bears,combined webelos.... first thro...

Re: Building It vs. Letting Your Child Build It
I teach parents to apply the rule of 20/40/60/80 as to the percentage of the total construction of the car. 20 percent tigers, 40% wolves, etc. Bearing in mind that pwd is a reoccuring event, tigers learn each year as they advance through the ranks. My son is a tiger, and on his black beauty green h...

Re: Shaping of wheels and other rule contradictions
One thing to remember, in the spirit of the Pinewood Derby... the original Pinewood Derby cars were pre-cut! :) A cool fact that I did not know. I learned something today. http://www.pinewoodpro.com/images/pinewood%20derby%20history%20-%20original%20car%20kit.jpg http://www.guitarattack.com/pinewoo...

Re: Shaping of wheels and other rule contradictions
I have not read the district/council rules. They do their derby at a "cub scout all nighter" that typically falls on one of our hockey tournament weekends. They also do not have any kind of "win in" to participate. If you want to run a car, then come to the lock in. Since we don...

Re: Master Schedule modifications needed?
I would like to be able to edit the master schedule. I think that being able to tweak the schedule after its generated benefits the event and the efficiency of staging cars without duplication between heats. Using the same data, exported to Excel, I came up with this: Group GREEN GOLD BLUE YELLOW 1T...

Master Schedule modifications needed?
I had a previous thread where I was concerned about the Master Schedule feature on GPRM not really doing alot to avoid consecutive heats. I understood the premise of the answer but I wanted to make sure we were looking at the same thing. parameters used: 6 lanes points scoring 1 heat per rank master...

Re: Potential Energy calculations requested
That was what I asked for in my reply email, as well as a profile drawing of the whole thing. Let us assume that it's 50% of the height at the bleachers, or about 2 ft 11" . Make it 3ft for easier calculations.

Re: Potential Energy calculations requested
Amazingly, a direct email to the architectural firm who designed the stadium was returned within hours: Length of stands = 140’ +/- Angle of incline = 21 degrees. Please keep in mind the seating is not a consistent angle. It changes to provide sightlines to the field from the different seating secti...

Re: Potential Energy calculations requested
An interesting related calculation would be the angle of a constant-slope section of track that allows a well-made car to roll at a constant speed. That would give you an idea of how to build a record-breaking track of arbitrary length. Start with a steeper ramp to get the cars up to speed, and the...

Re: Derby Magic Track
I watched that video twice, and perhaps they are using the same show twice where the car on the right of the video gets ridiculously squirrelly at the bottom of the Curve Section... not enough evidence to know.. I am curious to see the profile of the transition section from inclined to straight sect...

Re: Potential Energy calculations requested
While I await exact dimensions for ascending angle, distance to top of bleachers, and drop from front row to ground level, here is a photograph with the intended layout superimposed. More info as it becomes available.
