Damn have ypu been attending some of our meetings?
There are multiple advantages to the cast iron ( I believe they use grey cast iron disk. The following list comes from p76 http://www.sae.org/events/bce/tutorial-ihm.pdf
• High strength and...
A couple of things that caught my eye. Firstly, if you look at the TTC data for the tire you mentionned, the loads stop at 1200 N ( I believe the max on TTC tests is 1600 but in the case of the 10 in...

I think it has the flow rate. Some of the paintball guns have full auto and shoot at pretty high rates. Don't have any uppfront data but as far as I can...
For the exiting the track speed difference issue, is it possible to just make an extra lane.. offsets timing and driver change by 6-8 ft to the left.... So long as no one goes into that lane while on...
Talk to Scott at Taylor Race ( http://www.taylor-race.com/part.cfm?id=4708&category=Chain%20Drive%20%20%2F%20FSAE&subcategory1=Stub%20Axles%20Tulip&subcategory2=Tulip%20Style%20Stub%20Axles&popup=1)...
T3.5.5 If a bent tube is used anywhere in the primary structure, other than the front and main roll hoops, an
additional tube must be attached to support it. The attachment point must be the...
One thing to keep in mind is that most of the load ratings on rod ends are in tension loads. Most of the time it doesn't make a difference, sometimes, it can make your day a little more challenging...
The best reference I've found for sizing rotors is Rudolf Limpert's Brake Design and safety(there,s a copy at your uni's library). The third chapter on thermal design give some hand/Excel Calcs which...
i've used the PE3 a fair amount. While it's true that the data logging isn't as good as on a motec, it,s a good unit to get an engine running for a moderate amount. Also, their new firmware which is...
I stand corrected. As I said, heresay for the most part.And yes, getting top dead center with no reference tooth must be interesting.
For the trigger wheel issue, we never got to the point of solving it but from what I understand(spoke to a couple teams (Auburn in the case of this piece of information) that ran it in the past) it...
Yeah I was team lead at EPM last year and basically came to the point where the team was trying to make a cool car instead of scoring points. Me and my co captain decided to change that. Looked at...
Looks pretty sweet. For 200$ would definitely be worth it. Fair enough for the ground pin. On last year's loom I used one of these...
Only problem with DT series connector is that their load rating is 13A at max rated temperature. Obviously, I don't think your PDB is gonna hit 125 deg C but 70A through your ground pin might be a...
Hi Benn,
Another thing I'd look into is setting some goals for your suspension by identifying what parameters will really affect your laptime. OptimumLap would be a good place to start as it will...
The best way would be to put a connector there as it implies you can pull out the front and the rear of the loom separately to paint, strip change something on the car.
Secondly, the aeronautics...
WE managed to find a plastic injection place in our town tat makes cones for the construction industry. Now we have a pretty large stash
Another possible worst load case might also be when you (over)preload your bearings so you might want to be careful about that. We run 61913 bearings and doing the calcs, it came out to a life of...
Ended up doing the loom on the car this year. Picked up a couple cool references for anybody wanting to make a aeronautics grade wiring loom.
This and this should get you started. » Nasa also has...
Yeah the aeronautics stuff also has some part duty charts in there. As for weight of the wiring I did a quick MATLAB script to evaluate it and the wiring is something like 500g ( I range from 10AWG...
There s a company out there that sells twio stubs made out of 4340HT. Might want to look into that. Not a manufactuing guy but pretty sure you re gonna save some cash compared to buying the cutter...
If you really want to go bananas, it's possible to code one yourself. There is a fairbit of information in here here or here. I wouldn;'t recommend redoing the whole numerical bit because frankly...
Look up FAA AC43-13.1b.. Chapter 11. Gives you the slam dunk method to size wire.
It's an aeronautics method to size wire according to the FAA
