The primitive way concrete slabs are poured, you will never find a truly flat and level surface to work with in a typical workshop/garage/factory. Its not uncommon to see puddles over an inch deep...
I still think a gun driver with a bit of practice under his (her) belt will beat some computer nerd trying to adjust fifteen different variables on his keyboard while cornering at the max G.
Springs can vary quite a lot.
While the spring rate will be pretty consistent, depending on wire size, coil diameter, and number of coils, the free length and the loaded height can vary slightly...
This is interesting...

Now those curves are for a three phase induction motor that is rated to run at 60 volts nominal through some kind of variable...
Direct mounting the fan onto the core is very bad.
A very significant part of the core gets no forced air help at all, and the small area that does get all the forced air exhibits a higher air...
It's probably really a 100 Lb car with a 700 Lb driver.
If only two speeds are sufficient, how about just a hi stall torque converter plus a means of locking the converter solid with a parallel friction clutch?
You could even control the clutch with a...
This is very often done with small gasoline engines such as lawn tractors and golf carts by linking a "starter generator" with a vee belt to the original rope start pulley.
Just Google "starter...
Yes I would trust a well known reputable damper supplier that has carried out a lot of continuing R&D, and has had feedback from customers to provide a safe and reliable product capable of providing...
That sums it up very nicely Tim.
Spring and antiroll bar calcs are absolutely fundamental, and the results entirely predictable within a very close margin.
Definitely no argument on that score....
That is a very realistic assessment with which I wholly agree.
Golly Claude, do you mean that after all those calculations you still need to actually tune the dampers during testing.
WHY ???
Hint.
Pure design can take you a long way, but tuning is a very...
All this has one purpose, and one purpose only (for a race vehicle) to keep the tires in most intimate contact with the track and hopefully dissipate any excessive stored spring energy and resonance...
There are some very good practical real world reasons why that is so Karam.
The best approach would be to obtain some fully adjustable dampers with suitably wide adjustment ranges, and then do...
Chris, people here are student engineers doing their best to design a vehicle that is going to not only have to race, but be judged on it's technical merits by some very serious design judges.

Yes if it is a wet cell lead acid battery with removable tops and liquid electrolyte.
No if it is a fully sealed lead acid gell cell
Clever indeed.
And where are the front wheels or the front half of this car ?
Guys, something seems very wrong about all this.
Question Pat.
If you can get fridge magnets for free, do they really need to go into the cost report ?
You can clearly see the rose joints at the top of the coil shocks with a loose bolt, and no structure anywhere near there to bolt it to.
Not even a rolling vehicle I would say.
With that...
I am mystified by what structure supports the top of the coil shocks.
They just appear to sit there in clear open space attached to nothing.
And there appear to be two very long and loose bolts...
I have to agree with Z here.
The exactly equal torque fed to both rear wheels under any and all conditions that a fully open diff creates, cannot steer the car.
It is hardly surprising that...
Marcus, I had heard rumors that the Weismann diff worked something like a detroit locker with damping, but was not prepared to say so, because I did not know for sure and did not wish to cloud the...
And that is the whole problem Chris.
There is nothing really stopping anyone from buying one of your magic diffs and then pulling it apart to copy, or at least study and learn from.
In fact I am...
You are not supposed to say that, it is a very closely guarded secret that only winning teams know about.
