Hi MI906 (whoever you are...)

Hi Rodrigo,
getting back to the original topic:
I guess you were referring to some old posts by myself talking about hose problems.
The reasons for these posts are still very much there for mtb...
So, just speculating here, maybe some cars "had to be disqualified" in order to push some other cars up the rankings? I feel a conspiracy theory developing ;-)
Simple solution: Don't have dimensions relative to moveable/changeable components in the rules. Have a template that is essentially a plywood cutout. If you can fit your wing through it, ok, if not,...
Oh what a clusterf***...
My conclusion to this situation is the following:
1.) The way this rule is written makes it very hard to accurately take measurements that confirm or deny the rule...
The uprights you designed for that Formula Ford vehicle... I remember you telling stories about that in Russia!
Nevermind... I just used it as an example to make my point! Stiffness and fatigue...
Claude, I am afraid to say that but I think I disagree with your statement of your uprights still being too heavy because they didn't break.
An Upright is a stiffness driven component. So the...

This one: 440g full blown topology optimization with camber and toe...
Claude, I don't really understand (ünderstand? :D ) why you're going on about the impact attenuator. It's in the rules, appendix T-3: Standard Impact Attenuator. It is in there because the SAE wanted...
Every team I know of that has somehow created an engine model, have measured the camshafts themselves and flow-bench tested the head/ports...I'd say it is part of the challenge of FS to think up some...
Does the standard loom and ECU have a sidestand sensor? Usually, motorbikes cannot be started while the side stand is still out, and they have a sensor to detect that. If there is a place for it on...
Please, if you are trying to produce an accurate FE Analysis of anything, do not use SW but rather something with a decent preprocessor (Ansys, Hyperworks, whatever) where you actually have some...
You may have forgotten to add the driver weight, 220kg seems a bit optimistic for a first year, 4cylinder, spaceframed car on 13" tires, and I think you might have forgotten to factor the driver into...
I just found an online calculator for the brake bias and punched in some ballpark numbers (13" tires, 25.4mm caliper piston diameter with 2piston calipers...) , and this is what I got:
...
Wouldn't a very simple weight transfer calculation at 1g of deceleration be "cast iron" enough to convince the decision makers of the need to run different size master cylinders? This kind of...
Just a quick advice on the brakes issue: The usual way to do this is designing a brake system that already has the desired balance set via the components (piston diameters, rotor sizes etc...) and...
With these calipers it is highly likely that there is air in the system somewhere as they're next to impossible to properly bleed. The only reliable way I found after days of trying was to run brake...
Z, Menisk, others: Would you mind continuing your argument elsewhere, preferrably offline? It has kind of steered away from the original topic and onto general FSAE philosophy and rules committee...
Getting back to the brake MC setup: The configuration you mentioned can be achieved very conveniently with very tiny master cylinders like these for example:...
Marwan, Ahmad,
what you are doing here is finding false excuses for your lack of performance. Your car isn't good because you couldn't buy that Honda CBR in your country, or because the steel has...
I can't quite remember who it is exactly, but there are a few unis that actually run two teams on a two year cycle besides each other... Bath might be one of them I think.
Hi Marwan,
I really liked the phrase "...for taking selfies at the London Eye..." ;-)
But on a more serious note: Why don't you just jump forward yourself? Enter Class one and build the first...
I can only second Bemo's opinion on the Event. It was surprisingly well run (I expected way more chaos) and the atmosphere was great. There were a few minor glitches and delays but nothing to...
AMEN! Stupid Aero discussion...
GFR had an average laptime difference of 5.5 seconds in endurance at FSG, and almost 3 seconds in autocross. I am pretty confident that when you removed the wings...
While this statement is correct, the stiffness of 4130 (25CrMo4 for Europeans) is the same as mild steel. A chassis is usually designed with stiffness being the driving factor of development, and not...
