No need for such big surprise. I witnessed a similar number for "rule-of-thumb FOS" from my experience working at an engineering consulting firm. It's one of those "We don't have time for this, just...
Going back to the basics, Pat Clark's famous quote "A chassis is a bracket" should be the rule #1 for all chassis designers.
Have your sub system designs done (based on the overall design concept of...
Is it really linear? the load sensitivity index is a very small number. It may seem linear but when you fit a curve you'll find it otherwise.
Also... don't be trapped in a small domain for your...
And red flags???
More than anything though... this should have been covered during drivers meeting.
"If you see marshals running towards you, GET OUT AND RUN!!!!"
You'll get the most accurate answer by contacting the Formula SAE Rules Committee.
Meanwhile from what I know, the two bars at the top are not required by rule (but I haven't updated myself since...
Straight from the fresh 2017-2018 rule book which is exactly identical to the 2016 rules.
No mention of 'independent' suspension travel.
Typical example of not actually reading the rules...
This has to stop right now. I think SAE India allows the same wheel-to-wheel action for their competitions too.
Jay, if you have been directly involved with Indian students for an extended period of time, you'll understand where Claude's comments come from.
I went to a school where over 70% of the program was...
Hi, please use exactly 3.1415926535 teeth. Your team will take the 1st place easy.
I think you're still off point.
Is your team's 'big picture' goal having the lightest car possible? Or is it reducing weight in order to gain performance to win the competition?
In other words -...
Judge: "Hey, Why?" (pointing at the CF suspension tubes)
Student: "This carbon fiber suspension assembly reduced the toe compliance by xx.x% the camber compliance by xx.x% and unsprung weight by...
AG_, I got two things for you.
First, drop your pen, paper or CAD station, forget about the math and work on establishing 'proper' protocol for documenting design and communication.
If your team...
Generally if there is more than 2" gap from the exhaust and if the fuel tank is made of (or covered with) fire retardant material there should be no issue.
It won't affect anything for the tilt test as long as there is no leak.
For endurance, there would be an issue for fuel economy points.
Fuel economy is calculated by measuring the volume of fuel...
I'm very certain most teams with electronic shifters design/ make their own system.
Also, I wonder what makes it so difficult for you to go test the required torque by yourself.
And if you're the...
If you believe someone else can tell you what YOUR IDEAL should be, it could be one of the following:
You're underestimating the complexity of automotive system or just so naive to imagine there is...
Please... just go ask the rules committee...
Why are you wasting your time trying to argue with the people who didn't make the rules???
I see what RC is referring to. It's the front hoop bracing that is in multi pieces.
Your front hoop bracing support (meaning tubes that 'supports' the bracing) that connects the 'cut' and the upper...
Why the hell you need $70,000 to build a basic FSAE car anyway???
My team spent less than $20,000 for our first car FROM NOTHING (so it includes all the 'standard parts' engine, ecu, dampers, rims,...
Optimum G claims that OptimumLap will simulate lap times with 90% or better accuracy. At first it sounded strange to me because it's a point mass sim, it doesn't consider all that complex suspension...
If you're wondering whether the pressure is usually in much higher order (say 1000's of psi instead of 100's), the number is in the right ball park (I'm pretty sure most fsae cars will have the brake...
Why do you think it seems low?
The system pressure can be anything if it stops the car at the rate of deceleration you targeted.

When it happens, you have to engage the clutch again while in neutral to spin the gear for new position.
The video below may help you understand better.

Bemo, for sure any team can build an award-winning first car for any FS/FSAE competition for one reason: FS/FSAE competition is about engineering design, not motorsports or racing. As long as the car...
